Features and Functions
-
Used for direct drive systems that are directly connected to machinery.
-
Lineup featuring low-speed series with 1/2 the previous rated rotation speed.
-
Optimized electrical design eliminates the need for a large inverter, saving space for the control panel (Toyo Denki comparison).
-
Can be used as a substitute for induction motors at rated rotation speed taking "slippage" into consideration.
