CONTROLLER FOR HOIST CAPABLE OF MULTI SPEED CONTROL AND HOIST INCLUDING THE SAME CONTROLLER

摘要

The present invention relates to a hoist controller. The controller of the hoist according to an embodiment of the present invention includes: a rising button capable of adjusting a pressing degree; A down button capable of adjusting a pressing degree; A lift switch disposed under the lift button so as to operate immediately when the lift button is pressed; A lowering switch disposed under the lowering button to operate immediately when the lowering button is pressed; A magnet body operatively connected to both the rising button and the falling button and disposed to descend upon a pressing operation of the rising button or the falling button; And a hall sensor disposed in correspondence with the magnet body to sense the degree of descending by pressing by the up button or the down button of the magnet body. When the lift switch is operated by the lift button, the motor starts the lift operation, and at this time, the duty ratio of the pulse width modulated signal applied to the motor according to the output voltage changed according to the increase or decrease in the magnetic flux density sensed by the hall sensor By adjusting, the motor's rising operating speed is variable. When the lowering switch is operated by the lowering button, the motor starts lowering operation, and at this time, the duty ratio of the pulse width modulated signal applied to the motor according to the output voltage changed according to the increase or decrease in the magnetic flux density sensed by the hall sensor By adjusting, the motor's descending operating speed is variable.
