Problems solved by technology

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses a energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric torque. The existing motor equipment often has faults such as motor overheating and load running. Slow, electrified motor casing, etc., when the motor leaks and electrifies the casing, it needs to be powered off for maintenance, but at this time the casing is charged, and it is easy to cause electric shock during the operation. A leakage protection device for the motor casing described in the present invention can solve the problem of above question

Abstract

The invention discloses a motor shell leakage protection device. The device comprises a shell. A motor cavity is formed in the shell . A motor is positioned in the motor cavity. A through hole with aleftward opening is formed in the inner wall of the left side of the motor cavity in a communicating manner. The left end of the motor is in power connection with an output shaft. A connecting hole with a leftward opening is formed in the output shaft. The left end of the output shaft is in spline connection with a connecting shaft through the connecting hole. According to the invention, the electrification condition of the motor shell can be monitored in real time; the output of the motor can be automatically cut off under the condition that the shell is electrified, and meanwhile, the motoris completely separated from the shell, so that the shell can be quickly separated from an electrified state; an electric shock accident can be avoided; manual reset is needed after maintenance; and automatic reset and re-electrification of the shell in the maintenance process are avoided.

Description

technical field [0001] The invention relates to the field of motors, in particular to a leakage protection device for a motor casing. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses a energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric torque. The existing motor equipment often has faults such as motor overheating and load running. Slow, electrified motor casing, etc., when the motor leaks and electrifies the casing, it needs to be powered off for maintenance, but at this time the casing is charged, and it is easy to cause electric shock during the operation. A leakage protection device for the motor casing described in the present invention can solve the problem of above question. Contents of the invention [0003] In order to solve the above problems, this example designs a motor casing leakage protection device. The motor casing leakage protection device i...
