Title:
HIGH/LOW VOLTAGE COMBINED DOUBLE COMMUTATOR DIRECT CURRENT PERMANENT MAGNET ELECTRICAL MOTOR
Document Type and Number:
WIPO Patent Application WO/2014/089947
Kind Code:
A1
Abstract:
Provided is a high/low voltage combined double commutator direct current permanent magnet electrical motor, including a motor housing, magnetic steel, and a rotor mounted on a rotor shaft in bearings of a front and rear end cover. The wire slot of the rotor is embedded with a two-layer combined coil separately composed of a high voltage winding and a low voltage winding, and the high voltage winding and the low voltage winding are separately connected to a high voltage AC commutator and a low voltage DC commutator mounted at two ends of a coil hanging rack of the rotor; in carbon brush cylinders, which are symmetrically arranged at two sides of the low voltage DC commutator, between the housing and the front end cover and on a front end cover middle plate mounted on the rotor shaft, are arranged front end cover carbon brushes which are connected to front end cover leads of carbon brush terminals; and in carbon brush cylinders, which are symmetrically arranged at two sides of the high voltage AC commutator, between the housing and the rear end cover and on a rear end cover middle plate mounted on the rotor shaft, are arranged rear end cover carbon brushes which are connected to rear end cover leads of carbon brush terminals.The present utility model adopts a two-layer combined coil composed of a high voltage winding and a low voltage winding to constitute a high/low voltage combined double commutator direct current permanent magnet electrical motor, and can conveniently use an alternating current or a storage battery power source to provide power for an electrical motor.
