request details standard range of brushless servo motors up to 80Nm
view printer friendly page  

 

 

 

The AEG-Lafert standard motors are three-phase AC brushless servo motors with rare earth magnets for demanding servo applications. They offer an excellent price performance ratio and a wide range of standard configurations.

 

The brushless design means the motors are maintenance free. The motor flanges follow the typical European standards. The motor as standard offer 4 and 6 pole windings, some motors are also available with 8 poles.

holding brakes

The B series motors can be supplied 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.
