Unipolar-power rotary switch contact resistance motor

Abstract

The invention discloses a unipolar power supply rotary switch bumper motor. Its end cover (12) is arranged on both sides of the casing (1) with bolts, the copper sleeve (5) is fixedly arranged in the middle of both sides of the end cover (12), and the two ends of the rotating shaft (8) are movable on the copper sleeve (5). ), the stator (6) is fixed in the casing (1), the rotor (7) is fixed on the rotating shaft (8), and is movable in the middle of the stator (6), and the non-winding magnetic steel sheet (9) is fan-shaped , 8 poles are equidistantly arranged on the outer periphery of the rotor (7), 12-pole rectangular winding coils (11) are respectively arranged on the periphery of the stator (6), the controller (10) is arranged on the upper left end of the casing (1), and is connected with the stator (6) are connected and communicated, and the sensor (4) is fixed on the right end of the rotating shaft (8) and communicated with the controller (10). Because the rotor is designed as fan-shaped multi-poles with small gaps in the present invention, multi-poles can perform power supply at the same time, and a single winding can perform power in a single time, so that the starting current in the motor can be reduced by three times, and the torque can be increased, so as to achieve energy saving effect and solve the problem of Vibration and noise when starting and braking.

Description

Technical field: [0001] The invention relates to a unipolar power supply rotary switch bumper motor used in multiple fields such as industry, automobiles, household appliances, aviation, etc. Background technique: [0002] Energy is an important basic resource for the development of human society. With the development of the world economy, the rapid increase of the world population and the continuous improvement of people's lives, the world's energy demand continues to increase, which has led to increasingly fierce competition for energy resources. The environment Pollution is aggravating and pressure on environmental protection is increasing. At present, the prototype of domestic electric vehicles is generally 2 tons in weight, and the battery pack capacity is about 65mAh, and the battery is generally an acid battery or a lithium battery. The motor used is generally a switch bumper motor, and the rotor is a multi-pole protrusion. Type design, it is easy to vibrate when sta...
