Toyo Denki has nearly 100 years of experience as a motor manufacturer and was the first to offer a permanent magnet synchronous motor to the world. Our Dynamic Spin Dynamo (DSD) series employs our proprietary water-cooling method along with our permanent magnet synchronous motor.
Toyo Denki’s Dynamic Spin Dynamo (DSD) series has the lowest inertia in the industry. Our DSD is able to keep inertia moment to about 1/10th that of an induction motor with the same amount of capacity.
We were able to make our motor much more compact than the conventional one using our proprietary water-cooling method.
Toyo Denki has not only made the test system compact, but also engineered the frame structure to push the draft shaft and wheel base to the limit, achieving a layout that is equivalent to that of an actual vehicle.
In addition, our DSD is very quiet, making it highly suitable for use as a noise and vibration (NV) test bench.
