EV Bus

Dynamometer Test Bench for
Electric Bus Motors

Motomea supplies innovative solutions for e-Bus motor testing, optionally combined with HiL testing.

Solutions include Motomea's EV-RDS Four-Quadrant Operation & Braking, together with Motomea's worldwide patented IDS Acceleration Dynamometer, with unique dynamic capabilities.

Simulations include real-time simulation of vehicle/driver –to accelerate/to brake/to change vehicle states– and real-time simulation environment with full real-time capabilities.
