request details brushless servo motors up to 75Nm
view printer friendly page  

 

 

 

The BMZ motors are three-phase AC brushless servo motors with samarium cobalt magnets for demanding servo applications.

 

The brushless design means the motors are virtually maintenance free.

The motors are 4 pole for BMZ 29 ... 56 and 6 pole for BMZ 63 ... 100.

All are fitted with a 2 pole resolver.

holding brakes

The BMZ motors can be with a "zero-speed" holding brake. Please note that this option increases the overall length of the motors (see dimensions). Motor inertia and weight will also increase.
