Problems solved by technology

[0002] Various existing motors, such as AC induction motors, have simple structure and reliable operation, but they have difficulties in starting, large starting current, large power consumption, high calorific value, low efficiency, and difficulty in speed regulation.
Existing brushed and brushless DC motors include permanent magnet DC motors. Although they have higher working efficiency and easier speed regulation than the former, they have high calorific value, high cost, high failure rate, easy burning, difficult maintenance, and permanent magnet energy utilization. Low rate, large rotor inertia
[0003] The existing generators also have common disadvantages, that is, the motor is prone to heat, low efficiency, low utilization rate of permanent magnet energy, and high cost of use

Abstract

The invention provides a novel motor which comprise a motor casing, a stator and a cup-shaped rotor. The novel motor is characterized in that the cup-shaped rotor is provided with a magnetized multi-pole permanent magnet which is arranged on the cup-shaped cylinder wall; and the stator is provided with a stator outer sleeve which is arranged in a magnetic conductive cylinder, a coil skeleton is arranged in a stator inner sleeve, a plurality of groups of hollow coils are configured on the coil skeleton, the coils are configured at intervals, that is, the coils are arranged opposite to the inner peripheral surface of the permanent magnet and opposite to the outer peripheral surface of the permanent magnet simultaneously. The novel motor has the advantages that stator and rotor structures of a traditional motor are changed, and interaction of the coils with the permanent magnet is improved greatly by optimizing magnetic field distribution on coil tracks, accordingly, the motor efficiency is improved greatly, the starting current is reduced, and the power consumption is decreased. The stator coils are hollow coils, iron losses are decreased, the motor weight is lightened, the slot effect is removed, and the motor temperature rising is decreased simultaneously.

Description

technical field [0001] The invention belongs to the field of motors and relates to a permanent magnet motor / generator. Background technique [0002] Existing various motors, such as AC induction motors, have simple structure and reliable operation, but they have difficulty in starting, large starting current, large power consumption, high calorific value, low efficiency, and difficulty in speed regulation. Existing brushed and brushless DC motors include permanent magnet DC motors. Although they have higher working efficiency and easier speed regulation than the former, they have high calorific value, high cost, high failure rate, easy burning, difficult maintenance, and permanent magnet energy utilization. The rate is low and the rotor inertia is large. [0003] The existing generators also have common disadvantages, that is, the motor is prone to heat, low efficiency, low utilization rate of permanent magnet energy, and high cost of use. Contents of the invention [00...
