E-Motor Dyno Drive
E-Motor Dynamometer Drives to simulate realistic load and force on the E-Motor under test. Regenerative power, ratings up to 35,000 RPM, low intertia solutions, and works with any AC motor.
Develop and test your E-Motor by simulating realistic loads using Unico’s E-Motor Dyno Drive.
This proven E-Motor dynamometer drive is based on Unico’s successful 2400 series inverter, with installs throughout the world. It’s revolutionary technology provides superior control of three-phase AC dynamometer motors. High-switching frequency IGBTs deliver up to 30kHz for testing high speed E-Motors. Torque response in 1 millisecond gives exceptional control of speed and torque to replicate a wide variety or load, stress, and resistance on the E-Motor. NVH low noise operation and acceleration rates up to 300,000 rpm/second – perfectly suited quiet motoring tests and aggressive performance programs.

Testing Applications
Testing of traction / drive inverters before a real E-Motor is available. Validate the traction inverter to prevent expensive protoype E-motor failure due to incorrect inverter performance.
Precision Control and Flexibility
Unico’s E-Motor Emulator has a fundamental frequency of 1500Hz, emulates motors from 2 to 64 poles, and provides model calculation up to 30kHz. The silicon IGBTs provide a sampling frequency from 1 kHz (1.0 ms) to 10 kHz (0.1 ms), so you can replicate the quick response of a real E-motor to changing commands or load levels. Option the silicon carbide (SiC) MOSFET to emulate high speed E-Motors with even higher switching frequencies.
No moving parts means you’ll achieve a higher level of safety in boundary condition testing. And with more complete testing than HIL (hardware in the loop) or passive load emulation, it’s the ideal tool for EV propulsion engineers.
Preprogrammed
Fault injection verification makes it simple to track behavior and determine where error occurred: harmonics, 3 phase open circuit, phase to phase, phase to ground short circuit, motor stalling, motor over torque, winding asymmetry, demagnetization, sensor phase shift – it’s designed to help you go fast, and build the ideal traction inverter in less time.
User Programmable
Standard programmable parameters make it easy to test a varety of E-Motor designs with exact performance behaviors as a real E-Motor. Parameters include Direct Inductance Ld, Quadrative Inductance Lq, Magnetic Flux and Winding Resistance.
High Speed Link
Supports most industry standard communication protocol, making it versatile to work with any available automation system platform. A high-speed communications interface is optionally available to accept commands from existing customer controllers that are used to generate test profiles. Wired and fiber-optic options are available. Supported protocols include:
- CANopen
- CC-Link
- ControlNet
- DeviceNet
- Ethernet
- EtherCAT (async)
- Interbus
- LonWorks
- Modbus Plus
- Profibus DPV1
- Profibus Master
- EtherCat (sync)
Safety and Protection
Built-in safety and control interlocks are hardwired, opto-isolated, and software configurable to protect your investment and team. And with cabinet enclosure cooling options of air-cooled, water-cooled, and air-conditioned, this system will keep up with your testing and development program.
