Electric motor, has ventilator comprising rotor blades that are formed in such manner that ventilator has air-flow rate independent of rotation direction of rotor shaft of ventilator

摘要

The motor has a ventilator fixedly connected with a rotor shaft and comprising rotor blades (1), where the ventilator is designed as an axial ventilator. The rotor blades are formed in such a manner that the ventilator has air-flow rate independent of a rotation direction of the rotor shaft of the ventilator. Each rotor blade is symmetrically developed such that center plane is formed as normal merges after reflection at a rotor axis of the rotor shaft. The ventilator exhibits a ventilator ring that is radially connected with outer ends of the rotor blades.
