Abstract

The utility model belongs to the technical field of the high voltage DC motor, especially, be a groove coating rotor, which comprises a rotating shaft, fixed mounting has the rotor in the pivot, set up slottedly on the rotor, just the groove encloses 10 that revolute the sub-surface and be provided with evenly distributed, the utility model discloses adopt 10 groove chips, the main purpose with 700# electric motor rotor: firstly, the number of the slots is large, so that the motor commutation is facilitated, the working voltage of the motor is large, the spark is large, and the commutation spark of the motor can be reduced by adopting a chip with 10 slots, so that the performance of the motor is improved; secondly, the 10-slot rotor can adopt a symmetrical winding method, so that the initial balance of the rotor can be reduced, the improvement on the process is facilitated, and the production efficiency can be improved; thirdly, the adoption of 10 slots is also beneficial to the EMC of the motor, and the EMC test of the motor is better mainly because the reversing spark is much better than the slots.

Description

Slot coating rotor

Technical Field

The utility model belongs to the technical field of high voltage DC motor, concretely relates to groove coating rotor.

Background

With the progress of science and technology, the demand of high-voltage DC motors on the market is more and more, and the coating rotor with low groove number can not meet the performance requirement of the motors during operation.

SUMMERY OF THE UTILITY MODEL

For solving the above-mentioned problem that exists among the prior art, the utility model provides a groove coating rotor has the characteristics that reduce motor switching-over spark, improves the motor performance, extension motor life.

In order to achieve the above purpose, the utility model provides a following technical scheme: a slot coating rotor comprises a rotating shaft, wherein a rotor is fixedly mounted on the rotating shaft, a slot is formed in the rotor, and 10 slots are uniformly distributed around the outer surface of the rotor.

As the preferable technical proposal of the groove coating rotor of the utility model, the surface of the rotor and 10 inner surfaces of the groove are all coated.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses adopt 10 groove chips with 700# electric motor rotor, the main purpose: firstly, the number of the slots is large, so that the motor commutation is facilitated, the working voltage of the motor is large, the spark is large, and the commutation spark of the motor can be reduced by adopting a chip with 10 slots, so that the performance of the motor is improved; secondly, the 10-slot rotor can adopt a symmetrical winding method, so that the initial balance of the rotor can be reduced, the improvement on the process is facilitated, and the production efficiency can be improved; thirdly, the adoption of 10 grooves is also beneficial to the EMC of the motor, and the EMC test of the motor is better mainly because the commutation spark is much better than the grooves.
