Title:
HOLLOW-SHAFT ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/156094
Kind Code:
A1
Abstract:
The present invention provides a hollow-shaft electric motor, comprising a rotor (1), a stator (6), a housing (7), and a hollow shaft (3); the stator (6) is sleeved outside the rotor (1) and fixed in the housing (7); the rotor (1) is sleeved outside the hollow shaft (3) and fixedly connected to the hollow shaft (3); at least one end of the hollow shaft (3) is detachably connected to a connecting member (2) used for connecting to a load device. In the present invention, the hollow shaft is connected to the load device by means of the connecting member rather than directly connecting the hollow shaft to the load device, thus wear on the hollow shaft is prevented; since the connecting member and the hollow shaft are connected by means of a detachable connection, after the connecting member wears out, one must simply remove the connecting member and replace it with a new one; disassembly and maintenance are convenient, reducing maintenance costs.
