E-motor Emulator
E-Motor emulators for testing electric vehicle traction inverters. Validate and test inverter designs to prevent prototype e-motor failure.
Develop and test your EV / HEV traction inverters using Unico’s E-Motor Emulator.
This extraordinary E-Motor emulator is specifically designed for testing vehicle traction inverters without risking damage to a production E-Motor. The drive system acting as the emulator has a high switching frequency to replicate the exact power, voltage, and current demands of the E-motor. So you can test hundreds of traction inverter designs, and never worry about having an expensive E-Motor failure due to incorrect inverter performance.

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.
