Electromotive variable-speed and control drive particularly for use in industrial sewing machines |
摘要 |
An electromotive variable-speed and control drive particularly for use in industrial sewing machines comprising a motor capable of continuous drive with a disk flywheel and a brake-coupling unit connected to this motor. Cooling ribs confining cooling channels are disposed at the stator frame to achieve efficient cooling. A disk flywheel in the form of a fan is in the form of an axial-radial blower the suction area of which extends to the coupling surface of the disk flywheel. Furthermore, particularly intensive cooling of the brake end shield is possible.
