Abstract

The invention discloses a novel three-phase asynchronous motor stator winding method. The three-phase asynchronous motor stator comprises wire inlet terminals and wire outlet terminals, wherein everytwo of the wire inlet terminals are connected in parallel to form three phases, namely a U phase terminal, a V phase terminal and a W phase terminal; a star wiring method is adopted at the wire outletterminals. A four-level concentric and four-wire parallel winding method is adopted, magnetic poles formed by stator windings are used for distinguishing, the formed winding belongs to a consequent pole winding, and centralized windings are distinguished by the shape of the stator wings and an embedded wiring manner. The motor power and torque can be increased. Therefore, the method can be applied to a rotor winding of a large alternating current motor or an armature winding of a large / medium-sized direct-current motor.

Description

technical field [0001] The invention relates to the field of motor winding, in particular to a novel three-phase asynchronous motor stator winding method. Background technique [0002] Due to the higher and higher requirements for materials, the motor requirements for processing materials are also increasing, and the existing central coil of the motor cannot meet the high-efficiency cutting process. At present, the motor drives the stator with low power and small torque. For the processing of large cutting volume and hard materials, the coil is easy to burn out and cause a short circuit, which makes the motor unable to work. The present invention solves such problems by adopting a novel winding method, which ensures high power, high torque, and fast start-up acceleration, thereby ensuring the processing efficiency and service life of the machine. [0003] At present, the coils in the industry connect two coils belonging to the same phase in a pair of polar regions to form a...
