A Cooling Rare Earth Permanent Magnet Motor

Abstract

The invention discloses a cooling-type rare-earth permanent magnet motor, and the motor comprises a pedestal, bolt seats and a shell, wherein the shell is arranged at the upper side of the pedestal, and the bolt seats are arranged at the two sides of the pedestal. The beneficial effects lie in that the motor is simple in structure; the arrangement of a liquid inlet pipe, a liquid outlet pipe, a liquid storage tank, a micro pump, a heat dissipation pipe, heat dissipation fins, a heat dissipation cover and heat dissipation fins enables the heat, generated when the motor works, to be timely and effectively conducted out for dissipation, thereby greatly improving the heat dissipation efficiency of a device, and guaranteeing the normal work of the motor; the arrangement of a heating wire enables the motor to carry out heating and heat preservation in time in a low-temperature state, thereby reducing the temperature change of the permanent magnet, and avoiding the demagnetization of the permanent magnet; through the arrangement of a first temperature sensor and a display screen, the temperature change in the motor can be accurately measured, and data guarantee is provided for cooling orheat preservation adjustment of the motor.

Description

Technical field [0001] The invention relates to the field of permanent magnet motors, and relates to a cooling type rare earth permanent magnet motor. Background technique [0002] The rare earth permanent magnet motor is a new type of permanent magnet motor that appeared in the early 1970s. Due to the high energy product and high coercivity of the rare earth permanent magnet, the rare earth permanent magnet motor has the advantages of small size, light weight, high efficiency, and good characteristics. Series advantages. The existing rare earth permanent magnet motors have low cooling efficiency for the motor core, which increases the temperature of the core and affects the operation of the motor. At the same time, the existing permanent magnet motors lack heating and thermal insulation for the core under low temperature conditions. The device makes the permanent magnet temperature change greatly, causing the permanent magnet to demagnetize. Moreover, the existing permanent mag...

Problems solved by technology

The existing rare earth permanent magnet motor has low cooling efficiency for the motor core, which makes the temperature of the core rise and affects the work of the motor. The device makes the temperature of the permanent magnet change greatly, causing the permanent magnet to demagnetize. Moreover, the existing permanent magnet motor lacks a temperature monitoring device, so that the temperature inside the motor cannot be accurately measured, which affects the cooling and heat preservation adjustment of the motor. Therefore, it is necessary to A new type of device to solve existing problems
