Problems solved by technology

The insulation effect between the motor rotor chip and the rotor shaft, and between the enameled wire and the rotor chip generally leads to poor performance of the high-voltage test without breakdown and flashing of the rotor
The balance of the final rotor is average, and it is prone to vibration after a period of practical use
Therefore, the existing AC high-voltage high-power electric tool motor has the problems of low motor efficiency, general insulation effect and balance performance

Abstract

The invention discloses an AC high-voltage high-power electric tool motor, which comprises a stator (10) and a rotor (20), wherein the rotor (20) comprises a rotor shaft (21); the rotor shaft (21) isprovided with a commutator (22), rotor chips (23) and an output shaft (24) sequentially; the number of grooves of the rotor chips (23) is 14; the inner wall of each groove is provided with insulatingpaper (25); the insulating paper (25) is internally provided with an enamel wire; a baffle (26) matched with the insulating paper (25) is arranged at the groove; and the stator (10) comprises stator chips (11) matched with the rotor chips (23). The AC high-voltage high-power electric tool motor has the characteristics of high motor efficiency, good insulating effects and good balancing effects.

Description

technical field [0001] The invention relates to an electric tool motor, in particular to an AC high-voltage high-power electric tool motor. Background technique [0002] As one of the common application tools, power tools can be seen everywhere, such as electric drills, chainsaws, cutters, lawn mowers, etc. Electric tools have a wide range of applications, are important equipment in daily production and life, and play an indispensable role in social and economic development. The motor of the existing electric tool is usually a rotor with 22 slots, the production efficiency of this rotor is relatively low, and the copper consumption of the rotor is large, so the efficiency of the motor is low. Secondly, the insulation structure of the motor is general. The insulation effect between the motor rotor chip and the rotor shaft, and between the enameled wire and the rotor chip generally leads to poor performance of the high-voltage test of the rotor without breakdown or flicker. ...
