A rotor coil end insulation structure and motor

Abstract

The invention relates to an insulating structure for end parts of rotor coils, which comprises the coils, an insulating ring and a leaf spring, wherein insulating tapes are wound around end parts of the coils, one side of the insulating ring is fixed together with the end parts of the coils, the other side of the insulating ring corresponds to corresponding components at the end parts of the coils, two or more concave arc-shaped grooves are formed in the other side of the insulating ring, the leaf spring is arranged in the concave arc-shaped grooves, and the highest point of the leaf spring in the natural state is higher than the concave arc-shaped grooves of the insulating ring. According to the invention, the insulating ring is arranged between the end parts of the rotor coils and other components, and the leaf spring is arranged between the end parts of the coils and the other components, so that the insulating role is played, the contact or collision between the insulating parts at the end parts of the rotor coils of a motor and the adjacent components is buffered, the bump with the components is reduced, and the insulation to the end parts of the coils is protected. The invention further relates to a motor comprising the insulating structure for the end parts of the rotor coils.

Description

Technical field [0001] The present invention relates to motor manufacturing, in particular to an insulation structure at the end of a rotor coil and a motor. Background technique [0002] At present, after the end of the motor rotor coil is wound with insulating tape, due to the gap between the coils, an insulating fixed spacer is set between the coil and the coil to make up for the gap between the coils. However, the end of the coil is often suspended When the motor is running, especially for high-speed motors, due to motor vibration and other reasons, there may be contact or collision between the insulation of the motor rotor coil end and adjacent parts, causing insulation damage, which greatly affects the motor The service life and safe operation. Summary of the invention [0003] The purpose of the present invention is to overcome the above defects and provide a rotor coil end insulation structure and a motor with reliable insulation. [0004] In order to achieve the above obj...
