Abstract
Disclosed is a permanent-magnet DC motor particularly for driving an industrial sewing machine for saving energy. The permanent-magnet DC motor comprises a rotor, a stator, a front end closure and a rear end closure; front and rear bearings matched with the rotating shaft of the rotor are arranged on the front end closure and the rear end closure; a commutator, connected and contacting with a brush which is disposed inside the rear end closure, is arranged on the rotating shaft; the rotor is a metal cylinder adhibited with two permanent magnets; the stator is connected with the front end closure and the rear end closure, forming a sealed body, with only the rotating shaft exposed outside the holes of the end closures. A fan covered with an encloser is mounted on the rotating shaft outside the rear end closure and the encloser is fixed with the rear end closure. The permanent-magnet DC motor serves as a power source for the industrial sewing machine and can be started up and stopped immediately, thus obviously saving electricity. The main body of the motor is sealed, so fabric wadding and nap will not be sucked into the motor, thus prolonging service life.
Description
Technical field
The utility model relates to technical field of motors, especially relates to the outer permanent magnet DC motor of closure casing that a kind of fan places the motor main body.
Background technology
At present, the motor that industrial sewing machine adopts is the AC induction motor that a kind of clutch that has flywheel combines, and is open close by three-phase button control motor, and motor runs to come off duty from the working beginning always and just cuts out.And in the real work, the workman is when doing back work, and motor all is to be in the no-load running state, so caused very big waste of energy; If economize on electricity control, the time spent start, the time spent does not shut down, then because the starting characteristic of AC induction motor determines its starting back speed to rise slowly, start again after the shutdown, the workman can not work immediately, operates uncomfortable; Adopt the permanent direct-current electric function to overcome above-mentioned defective, but present permanent magnet DC motor, housing does not seal, and wadding suede can be sucked by motor, thereby causes motor to damage.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of permanent magnet DC motor is provided, be exclusively used in the energy-conservation driving of industrial sewing machine, synchronous working to reach, promptly open promptly and stop, no idling loss with sewing operation, and the motor seal performance is good, can not suck wadding suede, damage motor, long service life.
For achieving the above object, the technical solution of the utility model is such: a kind of permanent magnet DC motor is exclusively used in the driving industrial sewing machine; It keeps the structure of existing common permanent magnet DC motor basically, for preventing that fabric wadding suede is not inhaled in the motor, the motor main part is made enclosed, and fan is placed outside the motor sealing main body, the electric machine casing of being made up of stator by cooling quickens to dispel the heat.
Owing to adopted technique scheme, a kind of permanent magnet DC motor of the present utility model as the industrial sewing mechanomotive force, can be accomplished promptly to open promptly and stop, and economize on electricity obviously; The enclosed construction of motor main body is not inhaled in the machine fabric wadding suede, prolongs to use and raises life.
Description of drawings
