AC Motors

NIDEC MOTOR has been a world leader in developing and manufacturing commercial, industrial, and appliance motors and controls for decades. Their passion for designing solutions for everything that spins and moves drives their next-generation drive technology for an interconnected world.

Nidec is constantly improving their large AC motor line to keep up with customer demands. Their new TITAN vertical and horizontal AC motors feature a cast-iron frame, making it easier to assemble the winding and frame as a single unit. This reduces production time and increases speed-to-market for end users.

The cast-iron frame also delivers a more robust, rugged motor for demanding applications like water/wastewater, mining and oil and gas. Combined with the latest improved rotor fabrication process, these new motors deliver higher torque and superior performance than ever before.

Nidec also has a range of brushless AC servo motors suitable for a wide variety of automation and motion control applications. They offer compact footprint, high torque, low inertia, and advanced motor control technology to suit your unique needs.

At some point in their service life, all induction motors will be operated on circuits of voltage and frequency that are other than those for which they are rated. These operating conditions cause small changes in the motor performance. Generally, these minor variations in operation will not cause damage, but over extended periods of time they can lead to heating and accelerate the deterioration of the insulation system.

When operating at a lower than rated speed, the regenerative current from the motors will flow back through the input rectifier of an AC drive, producing more power losses than at a normal load. The difference between the rated and operating currents is the amount of lost energy, called power factor. This can be improved by using a DC drive with an active braking resistor.

Nidec offers world-class matched solutions that bring together Control Techniques’ AC drives and U.S. Motors’ severe duty cast iron and vector duty steel and aluminum induction motors to make your selection easy. The Commander C200 general purpose AC drive has been paired with the Unidrive M700 high performance AC drive and the ACCU-Torq severe duty cast iron and vector duty induction motors to deliver an integrated, single-source solution.
DC Motors

As an industrial motor manufacturer, Nidec produces DC and AC Motors for use in a wide range of applications. The company’s motors, drives and generators are found in computers, smartphones, home appliances, automobiles, manufacturing plants and robots. The company generates over B in annual sales from its extensive product offerings.

The basic components of a DC Motor include the rotor, which creates mechanical rotation, and the stator, which provides electrical power. The rotor is made of multiple disks that are insulated from each other to prevent the creation of large eddy currents. The insulated disks also reduce the size of the magnetic field created by the rotor, which increases the speed at which the motor can turn and perform torque control. acim app

When the armature of the motor is rotating, it cuts through the magnetic flux lines that are induced in the stator core. This induces a back emf in the conductors of the armature, and according to Faraday’s law of electromagnetic induction, the direction of this back emf is opposite the direction of the armature current (Ia). The magnitude of the back emf is proportional to the speed of the motor. As the motor slows down, the armature current decreases and the motor’s torque reduces.

The armature of the motor is connected to the DC supply via brushes that are attached to the commutator. The commutator changes the AC current from the brushes to a DC voltage that is applied to the armature coils, thus enabling them to produce torque. As the rotor rotates, the brushes move to the next set of commutator contacts and energize that winding, causing a flip in the direction of the magnetic field of the rotor and prompting it to keep turning.

SR Drives is a division of Nidec Motor that specializes in switched reluctance motor technology. The company has developed a number of easily configurable, digital or hybrid drives that are compatible with SR motors. Using these drives can improve efficiency, extend the life of your motor and reduce maintenance costs. They can also allow you to achieve greater dynamic performance than you would otherwise be able to with traditional AC or induction motors.
ACCU-Torq® Induction Motors

The AC induction motor has a copper wound stator and a rotating magnetic field that generates torque. Induction motors do not require brushes and have low maintenance costs. They are used in applications such as pumps, furnaces, ovens, off road equipment and more.

Induction motors have a specific voltage per frequency ratio (V/Hz) that defines their power rating. The V/Hz ratio is directly proportional to the amount of flux in the motor magnetic material (stator and rotor core laminations). The more magnetic material, the higher the flux, which equates to the higher the torque capability.

When the VFD supply current reaches rated voltage and frequency, the motor can develop any amount of torque up to the maximum allowed speed at rated power. This area of the motor torque-speed curve is called the constant torque region or constant power area. Above the rated motor speed, the V/Hz ratio decreases and the magnetic flux reduces. When the magnetic flux density is lower, the motor will experience overheating and the V/Hz must be reduced to prevent saturation of the rotor and stator magnetic materials.

During initial startup, the motor’s current rises to multiple times its rated value. As the rotor starts turning, the magnetic field in the rotor core and the stator poles align with one another. The energized poles create magnetic fields that rotate, creating torque. As the rotor turns, different windings are sequentially energized, creating new magnetic fields to keep the rotor spinning.

To achieve this, the VFD must use a current control strategy that is optimized for the particular motor. For example, it may need to be a full closed-loop current control system to accurately model the magnetic saturation and skin effect of the rotor and stator.

US Motors offers a line of AC induction motors designed to work with the power factor correction of an inverter or vector drive. These ACCU-Torq motors can be ordered with an encoder and brake pre-assembled, eliminating the need for additional wiring and reducing installation time and cost. Ask your sales representative about our range of ACCU-Torq AC motors that offer high performance and a wide range of speeds.
Motion Control

Motion control is a system of hardware and software that coordinates multiple motors to achieve a particular trajectory or position. The system also provides feedback to ensure the motion is accurate and precise. The key components of a motion control system include the controller, drive/amplifier and servo motors.

The controller is the brain of a motion control system and controls all of the other devices in a production line or machine. It receives instructions from, and provides feedback to, the main computer that controls the entire production process.

There are several different types of motion controllers, each with its own set of capabilities and features. For example, there are microcontroller-based controllers, which combine electronics and external connections on a single circuit board. They are often used to generate and execute motion profiles in a simple, cost-effective manner. Then there are programmable logic controllers (PLCs), which use high-performance processors to perform complex functions, such as coordinating multiple motors.

A drive/amplifier is a device that converts the low-energy reference signals from a controller into the high-energy voltage and current required to power the motor. It is a crucial link in a motor control system and may be either analog +/-10 VDC or digital. The analog signal is most common but digital network interfaces are now becoming more popular.

Servo drives can be used to control velocity, position or both. acim nidec offers a wide variety of servo drives that work with any of our motors.

When controlling more than two axes, it’s important to consider the type of interpolation control that will be implemented. This will determine how quickly the axis can move and what the maximum speed is.

At acim nidec, we’re focused on helping you achieve your dreams of awe-inspiring automation and robust robotics. That’s why we provide an array of development platforms for prototyping and proof-of-concept applications. For example, our quad-motor control design platform uses the i.MX RT crossover MCU and EdgeLock® SE050 secure element, to enable multi-motor control with deterministic communication and IEC 62443 security compliance.
