PMSM Motor

Testing Systems for Permanent Magnet Synchronous Motors

Permanent Magnet Synchronous Motors (PMSM's) are brushless and have very high reliability and efficiency. Due to their permanent magnet rotor, they also have higher torque with smaller frame size and no rotor current, all of which are advantages over AC Induction Motors (AICM's). With their high power-to-size ratio, PMSM's can help make your design smaller without the loss of torque. PMSM's need to be commutated like BLDC motors, but due to the construction of the windings, the waveforms need to be sinusoidal for good performance.

Motomea supplies systems and solutions, including customized solutions, for all PMSM applications

PMSM: Key Applications

Automotive (Drive system for all types of Electrical Vehicles)

Motomea Electric Vehicle and Traction Motor laboratory systems include the capabilities for testing high-speed, high-torque electric vehicle (EV) motors, in laboratory applications. These capabilities overcome some unique challenges, due to the unique motor applications, such as: high power densities, high speed ranges, high torque ranges, robustness, and more. Motomea’s solution for this special requirement provides capabilities that enable testing EV motors of a maximum power of 200 kW at 24,000 rpm, and a power of 100 kW at maximum speed of 36,000 rpm. Motomea provides PMSM test stands that allow the user to test motors for performance, efficiency, or endurance, for any type of R&D or EOL requirements. The PMSM test stands are controlled with the Motomea RDS software. The data-acquisition is done with the software and you can also automate your tests with it.

Automotive (Drive system for all types of 2- & 3-wheelers)

Motomea Electric Vehicle and Traction Motor laboratory systems include the capabilities for testing and mapping of performance parameters of EV traction motors. Motomea’s solutions for this are systems designed for evaluating multiple types and multiple manufacturers’ motors, with ranges of up to 25 kW, of up to 80 V, and max speeds of up to 15000 rpm. Motors are driven by their respective controller, with different types of communication protocols (CAN, LIN, A/D, FlexRay, Speedgoat, Modbus, etc.)

Aerospace (Drive system)

Motomea Aerospace laboratory systems include the capabilities for testing motors from 1 kW up to 360 kW, with their hardware. The systems are used to test the different electric hardware applications and motors at laboratory settings, simulating the real-life conditions they will have while implemented in their final applications.

Applications: electrical unmanned aerial vehicles (UAV), electrical passenger planes, military applications, and other.

Power Plant & Aerospace Actuators

Motomea Power plant laboratory & Aerospace actuators systems include the capabilities for testing full performance of synchronous motors (PMSM), from 1 kW up to 140 kW, with their hardware. The systems are used to test actuators, optimized for high-force and precision, in a compact footprint, making them ideal for power plant and aerospace & aviation applications.

Applications: airplane landing gear and access doors actuation system, helicopter motion control (rotor blade, trailing edge flaps, onboard beam control, and gear and access doors.), and other.

Automotive Electrical Power Steering, including ePRCB (Electric powered re-circulating ballscrew)

Motomea Automotive laboratory systems include the capabilities for testing electrical power steering, including ePRCB with their hardware. The systems are used for NVH (Noise, Vibration, Harshness) tests, using tri-axis force & vibration sensors; dynamic tests, using two-side loading with very high accuracy speed & torque sensors; and friction tests.

Applications: automotive electric vehicles (EV), and other.

Home Appliance

Motomea Home Appliance laboratory systems include the capabilities for testing refrigerator compressors & direct-drive washing machines, from 30 W up to 3.7 kW, with their hardware. The systems are used to test the different electric hardware applications and motors at laboratory and at production line (EOL systems).

Applications: direct-drive washing machines, refrigerator compressors, air conditioners, and other.

All MUT's (Motors Under Test) can be controlled via CAN, PWM, analog, and other types of communication protocols.
