Novel motor

Abstract

The invention provides a novel motor. The novel motor comprises a motor shell, a stator and a cup-shaped rotor. The novel motor is characterized in that a magnetized multi-pole permanent magnet is arranged on the cup-shaped cylinder wall of the cup-shaped rotor, a magnetic permeable cylinder is arranged on a stator jacket, a coil bobbin is arranged inside the stator jacket and provided with a plurality of sets of hollow coils, and the coils arranged on the inner wall of the inner cylinder of the coil bobbin are opposite to the corresponding coils in the radial direction on the outer wall of the outer cylinder of the coil bobbin. The novel motor has the advantages that a stator and rotor structure of a traditional motor is changed, the magnetic field distribution on a coil track is optimized, the mutual effect of the coils and a permanent magnetic field is improved greatly, and therefore efficiency of the motor is improved greatly, the starting current is reduced and the power consumption is reduced. Due to the fact that the coils of the stator are hollow, iron loss is reduced, the weight of the motor is reduced, the slot effect is eliminated, and the temperature rise of the motor is lowered at the same time.

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.
