Self-heat-dissipation system for switched reluctance motor

Abstract

The invention discloses a self-heat-dissipation system for a switched reluctance motor. The self-heat-dissipation system comprises a switch reluctance motor shell, the switch reluctance motor shell issleeved with a fixing plate., the fixed plate is fixedly connected with the switched reluctance motor shell, a heat conduction plate is fixedly connected to the inner side of the fixed plate, a cooling pipeline is arranged in the heat conduction plate, a circulating water cooling mechanism communicated with the cooling pipeline is arranged on the outer side of the fixing plate, a rear cover shellis arranged at the rear end of the switched reluctance motor shell, the switched reluctance motor shell is detachably connected with the rear cover shell through a mounting mechanism, and a heat dissipation mechanism is arranged in the rear cover shell. The self-heat-dissipation system is reasonable in structural design, the purpose of circuit conduction is achieved through mercury rising along with temperature rising of the switched reluctance motor, the good heat dissipation effect of air cooling heat dissipation and water cooling heat dissipation is achieved, the temperature in the switched reluctance motor shell is prevented from being too high, and operation of the switched reluctance motor is facilitated.

Description

technical field [0001] The invention relates to the technical field of heat dissipation equipment for switched reluctance motors, in particular to a self-radiation system for switched reluctance motors. Background technique [0002] Switched reluctance motor is a type of speed regulating motor developed after DC motor and brushless DC motor. Has been widely used in household appliances, aviation, aerospace, electronics, machinery and electric vehicles and other fields. [0003] Switched reluctance motor is a new type of speed control motor, which is the latest generation of speed control system following frequency conversion speed control system and brushless DC motor speed control system. It has simple and firm structure, wide speed range and high system reliability. The complete system mainly consists of motor entity, power converter, controller and position detector. The controller contains the power converter and control circuit, while the rotor position detector is i...

Problems solved by technology

[0004] In the prior art, the switched reluctance motor will generate a lot of heat during operation, and the heat will accumulate, which will easily affect the normal operation of the switched reluctance motor, and even cause damage to the internal components of the switched reluctance motor, resulting in The motor cannot be used normally, and the existing switched reluctance motor is only cooled by air through the cooling fan installed inside the rear cover. Numerically, for this purpose, a self-cooling system for switched reluctance motors is proposed
