Abstract
Provided is a stator punched sheet and a rotor punched sheet of an injection molding machine motor. A stator punched sheet and a rotor punched sheet are included. Stator grooves are arranged around a circular hole arranged in the center of the stator punched sheet. A shaft hole is disposed in the center of the rotor punched sheet while rotor grooves are uniformly arranged around the rotor punched sheet. The stator punched sheet is characterized in that 72 stator grooves are arranged on the stator punched sheet, that a stator groove has an arc-shaped top, two inclining sides inclined inwards, and a bottom with an opening, and that two inward bumps are arranged at the opening to form a pyriform half-sealed mouth. 60 rotor grooves are arranged on the rotor punched sheet and a rotor groove has a top with an opening, a straight side and a gradually-increasing stepped side, and a shrunk bottom forming a knife-shaped groove.
Description
Technical field
The utility model relates to the injection molding machine motor, particularly relates to a kind of stator and rotor punching of injection molding machine motor.
Background technology
The injection molding machine motor is to be specially to require the motor load noise low by the supporting motor of injection molding machine.And injection molding machine motor frequent overload in the course of the work, power of motor reaches 1.6 times of rated power during overload, and the stator of existing injection molding machine motor adopts the stator punching of 72 grooves; Stator slot shape top is circular; Both sides are short lines, and rotor adopts the rotor punching of 58 grooves, and rotor is U type structure; At the bottom of its bottom land was arc, the motor load noise of this structure was bigger; Satisfied not customer requirements.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that prior art exists, a kind of reduction noise of motor to be provided, reducing the impulsive magnetic field intensity in the air gap; The groove area utilance is high; Life of Punch Die is long, and the slot liner degree of crook is little, not cracky; Reduce starting current, increase the stator and rotor punching of a kind of injection molding machine motor of detent torque.
The technical scheme of the stator and rotor punching of a kind of injection molding machine motor of the utility model is: comprise stator punching and rotor punching, in the middle of stator punching, open circular hole, the circular hole periphery has stator slot; In the middle of rotor punching, open axis hole, be evenly equipped with rotor around the rotor punching, it is characterized in that having on the said stator punching 72 stator slots; The top of stator slot is an orthodrome, and both sides are the hypotenuse in being tilted to, and the bottom is a under shed; Opening part is shaped on two inside projections, forms the semi-closed port pyriform, has 60 rotor on the said rotor punching; The top of rotor is upper shed; One side is a straight flange, and opposite side is the step limit that increases gradually, and the bottom dwindles the knife-edge groove of formation.
The utility model discloses a kind of stator and rotor punching of injection molding machine motor, the number of stator slots of stator punching is 72, and every extremely every phase groove number is 4, belongs to the integer groove, but choose reasonable winding configuration and winding pitch; Reduce noise of motor, stator slot shape adopts the semi-closed port peariform slot, the parallel teeth design, and its stator slot lower opening is little; Lower opening is shaped on two inside projections, can reduce the impulsive magnetic field intensity in the air gap, and tooth portion magnetic flux distribution is reasonable, helps reducing electromagnetic noise; Carter's coefficient is less, can reduce exciting current, and simultaneously, the groove area utilance is high; Life of Punch Die is long, and the slot liner degree of crook is little, cracky not, and electrical machinery life is long; The rotor number of rotor punching is 60, cooperates with 72 stator slot, helps reducing electromagnetic noise, and rotor slot shape adopts the knife-edge groove, and in the electric motor starting process, it is obvious to squeeze the stream effect, reduces starting current, increases detent torque, and the punch die manufacturing is simple.
The stator and rotor punching of a kind of injection molding machine motor of the utility model, described rotor opposite side step limit is the step that twice increase gradually.Said stator punching periphery is shaped on 9 stopper slots.
