  • Special Features
  • Specification

The EPT Series provides a complete electric motor and inverter testing ecosystem that mirrors real-world driving demands. It combines dynometric loading systems, rapid control software, power electronics simulators, and real-time analytics to evaluate performance, efficiency, thermal stability, and system safety.

Engineers can build detailed test cycles using drive-profile simulation, capture raw electrical and mechanical signals with high-speed synchronization, and analyze behavior down to transient response events.

The platform is adaptable to multiple EV architectures, including 400 V and 800 V systems, BSG/ISG mild-hybrid drives, and heavy-duty traction motors. Automated load/unload and labeling options support efficient end-of-line workflows for manufacturing facilities.

Optional climate chambers, coolant conditioning, and vibration modules extend testing into durability and environmental validation — ensuring product readiness for global operating conditions.
