Abstract

The invention relates to a motor with an electrically slipping rotor spindle, which is composed of a rotor (25), a stator and a slip drive mechanism, wherein one end of a rotor spindle (6) of the rotor is provided with a drive gear (28) for outputting torque, and the other end is provided with the slip drive mechanism mainly composed of a screw rod (22), screws (18), an auxiliary rotor (14) and an auxiliary stator; and the screws (18) are axially arranged on the auxiliary rotor (14) and connected with the screw rod (22) through threads. When the auxiliary rotor (14) drives the screws (18) to rotate, the screw rod (22) matched with the screws is caused to linearly move axially so that the rotor spindle (6) produces axially slip of which the position is detected by a plurality of position sensors (16) arranged on the end of the motor. The motor has compact structure and can simplify the structure of a machinery drive system when being used in change drive or multi-position drive machinery.

Description

technical field

[0001] The invention relates to a motor for electric sliding of a rotor shaft. The electric motor is used in electric-driven multi-transmission chain mechanical equipment, and is especially suitable for the transmission system of rapier looms. Background technique

[0002] Transmission devices driven by electric motors are widely used in mechanical equipment. The rotor shaft of a general motor is fixed relative to the stator in the axial direction. When the mechanical device needs to be driven by a time-sharing multi-transmission link, the intermediate gear is usually used to change the transmission route, and a corresponding fork operating mechanism is provided. The other The method is to set the clutch to split the transmission link. The mechanical structure of these variable transmission chain drives is complex. In some applications, the driving gear on the rotor shaft of the motor can be directly moved to change the transmission chain. For example, in ...
