Abstract

The present invention relates to a DC motor for hoist machine that is essentially a design of applying DC brushless inverter motor in the hoist machine. The stator and rotor of the brushless motor are formed in such a manner that a plurality of magnets are placed with alternation in polarity into the inside of the rotor of motor to generate main magnetic field, and that a current is supplied to the windings inserted within the block made of silicon steel lamination to exert push force. The integration of the application of DC brushless inverter motor combined with the electric and electronic elements gradually brings about inverter-controlled technology with maturity, by which excellent energy-saving effect can be obtained in case of the application having variable load, due to the fact that the inverter control has better manipulation property and better features of motor-output, and possesses high torque-output and better manipulation property in low-speed of rotation running condition. Furthermore, a speed-regulation button is provided on the push button switch of the present invention, by which the rotation speed can be regulated directly so as to increase the entire performance in use.
