Abstract
The utility model relates to a by-passed magnetic type self-braking asynchronous motor with a cone end. One end of a rotor of the utility model is conical. By applying the utility model to an electric hoist, the glide amount can be reduced, and the impact and the strip breaking of the rotor are avoided. The utility model originates a new road to the braking motor.
Description
The utility model belongs to electric motors.
The motor of electric block use at present has two kinds, and a kind of is conical rotor motor, and another kind is other magnetic-type motor.
The characteristics of conical rotor motor are, can produce axial magnetic pull, have the automatic brake ability, but its manufacturing process complexity are difficult to realize semi-automation or automated production.Other magnetic-type motor has the big characteristics of braking force, but its bump is serious, noise greatly, can make rotor broken bar sometimes, the end ring fracture.
The purpose of this utility model makes the matching used motor of electric block.
The first, have enough axial magnetic pulls, satisfy brake request and surplus energy arranged, use reliable.
The second, have easy structure and technologic simplification, can automation or semi-automatic production.
Three, start a new road for brake motor.
The other magnetic-type self-retention of end awl asynchronous motor rotor silicon steel sheet is manufactured the silicon steel sheet manufacture method of employing garden cylindricality motor, i.e. " one falls three " formula silicon steel sheet blanking, rotor dashes with deep trouth, identical with the deep trouth motor rotor punching sheet, casting aluminum rotor then, go out to hold the tapering with the lathe car, at this moment rotor equally has axial magnetic pull with cone rotor, end face also has other magnetic action simultaneously, its rotor rolls off the production line with garden post machine, process the brake body that can be inhaled symbol by end face that other magnetic-type motor is the same in addition, be fitted on the armature spindle with compression spring and bore a side by rotor-end, inhaled when symbol compaction pressure spring at brake body, make the brake body of end toper rotor end-face be inhaled the symbol end face and be close to, the brake body other end has braking ring, when braking, compress the inboard corresponding component of End cover for motor because of the compression spring effect makes braking ring, the inboard of ring has blade, plays the fan effect during rotation.
Technical essential of the present utility model is, rotor is an end toper, and the tapering of its rotor-end is between 10 degree～25 degree.
Owing to the utility model, combine the advantage of conical rotor motor, other magnetic-type motor deep bar rotor motor and garden cylindricality motor, so its axial magnetic pull is very big, has satisfied brake request, easily realizes automation or semi-automatic production.
Accompanying drawing of the present utility model 1 is the other magnetic-type self-retention of end awl Induction Motor Structure schematic diagram: 1, arbor, 2, fan guard, 3, fan blade, 4, left end cap, 5, fan, 6, end ring, 7, balance columns, 8, stator, 9, end awl rotor, 10, fin, 11, end wimble fraction, 12, brake disc rotating ring, 13, compression spring, 14, brake disc, 15, feather key, 16, bearing, 17, right end cap.
The utility model can have two kinds of implementations, and one adopts taper awl motor thrust bearing and brake apparatus to realize, the other magnetic-type motor of its two employing assembling method is realized.
The utility model embodiment sees accompanying drawing 1, from drawing as can be seen, after energising, rotor produces very big axial magnetic pull and other magnetic action, the brake disc rotating ring is drawn in bore of stator Nei And inhale symbol on the rotor-end awl, brake disc rotating ring compaction pressure spring at this moment, brake off state, outage back compression spring makes the brake disc rotating ring break away from bore of stator, brake disc depended on pressure spring action friction catch on the right end cap inwall.
Claims (2)
1, by arbor, fan guard, fan, end cap, fan blade, end ring, balance columns, stator, rotor, fin, brake disc rotation change, compression spring, brake disc, feather key, bearing, the other magnetic-type self-retention of the end awl asynchronous motor formed, it is characterized in that: rotor is an end toper.
2, the other magnetic-type self-retention of end awl according to claim 1 asynchronous motor, the tapering that it is characterized in that rotor-end is between 15 degree～20 degree.
