High-safety switched reluctance motor

Abstract

The invention relates to the field of motors, and in particular relates to a switched reluctance motor. The motor includes a stator, a rotor iron core, a rotating shaft, and a housing fixed outside the rotor. The rotating shaft sleeves the rotor iron core. An insulating part is arranged between the rotor iron core and the rotating shaft. The insulating part is arranged between the rotor iron core and the rotating shaft, so the insulating properties of the switched reluctance motor are improved. The rotating shaft of the switched reluctance motor is not electrified and meets the requirements of II type tools, so the safety performance of the switched reluctance motor is improved. The application range of the switched reluctance motor is increased.

Description

technical field [0001] The invention relates to the field of motors, in particular to a high-safety switched reluctance motor. Background technique [0002] Switched reluctance motor is a new type of speed regulation motor. The speed regulation system has the advantages of both DC and AC speed regulation systems. It is the latest generation of stepless speed regulation system following the frequency conversion speed regulation system and brushless DC motor speed regulation system. It has simple and firm structure, wide speed regulation range, excellent speed regulation performance, high efficiency in the whole speed regulation range, and high system reliability. [0003] The rotor of the switched reluctance motor in the prior art, the rotor iron core and the rotating shaft are directly hot-pressed and interference fit, the processing technology is difficult, and there is no corresponding insulation protection, especially the switched reluctance motor applied to the electric ...

Problems solved by technology

[0003] The rotor of the switched reluctance motor in the prior art, the rotor iron core and the rotating shaft are directly hot-pressed and interference fit, the processing technology is difficult, and there is no corresponding insulation protection, especially the switched reluctance motor applied to the electric tool, even if Use an insulated casing, and the gearbox needs to be grounded. If there is no grounding, the operator may have an electric shock accident, and the rotating shaft may be charged with static electricity. Even if the gearbox is reliably grounded, the operator will still There may be a danger of electric shock, and it belongs to the industrial tool; if the grounding wire is added, the manufacturing cost of the cable will be increased; at the same time, the rotor core and the shaft adopt interference fit, which not only requires higher processing requirements for the shaft, but also increases the switch magnetic field.
