SENYD BTH6 high-power synchronous servo motor, 1.5 MW, 10,000 rpm, for test bench applications.

High-Power Synchronous Servo Motor

SENYD high-power motors are designed to provide direct-drive solutions for various large-scale test benches. At present, we are able to deliver dynamometer systems for the most complex testing applications with power up to 1.5 MW and rotational speeds up to 10,000 rpm. These systems are widely used in new energy vehicle testing, aerospace testing, axle testing, heavy-duty trucks, and construction machinery testing.
