Inverter-driven electric motors are the core of modern EV powertrains, requiring precise validation to ensure efficiency, performance, and reliability. Traditional testing methods using physical motors and dynamometers introduce mechanical losses, setup complexity, and safety risks, limiting flexibility in failure mode analysis and high-speed transient testing. E-Motor emulation eliminates these challenges by electronically replicating motor behavior, enabling controlled, repeatable, and highly accurate inverter testing under real-world conditions. By simulating back EMF, RL loads, and dynamic torque response, an emulator allows engineers to optimize motor control strategies, validate drive algorithms, and conduct fault injection testing without physical hardware limitations. UNICO’s TST800 E-Motor Emulator provides a high-fidelity, software-defined platform for advanced traction inverter validation, delivering precision, scalability, and safety beyond traditional test setups.
The TST800 E-Motor Emulator is a high-precision solution for traction inverter testing, eliminating the need for a physical motor. Designed for three-phase AC load emulation, it supports a fundamental frequency of up to 1500Hz and motor emulation from 2 to 64 poles, ensuring accurate back EMF replication, RL load simulation, and dynamic torque modeling.
Engineered with SiC-based switching technology, the TST800 delivers high-speed response, low-loss operation, and precise power conversion, making it ideal for high-speed EV motor and inverter validation. With real-time model calculations up to 32kHz, it enables fault injection testing, allowing engineers to assess inverter performance under dynamic failure conditions. The solid-state design, free from mechanical components, enhances safety, reliability, and repeatability, offering a more advanced validation platform than HIL or passive load emulation. Built for scalability and seamless integration, the TST800 is the ultimate solution for power electronics engineers focused on high-fidelity inverter testing and e-motor control validation.
