Description of AC servo motor EM3J-10

EM3J-10 is a high speed and medium inertia 1000 W synchronous AC brushless servo motor. The motors can be equipped with 17-bit magnetic or 23-bit optical absolute encoder.

Independent electromagnetic design improve rotor rotation inertia. Inherit all the advantages of EM3A series, but with higher inertia. This high speed series offers a range of output power and different encoder types.

Optional 24 VDC brake is available.
