摘要： A non-excited operation type electromagnetic brake control device and method which are free from vibration noise and frequent switching when reducing average current which flows through a brake coil in a holding state of a non-excited operation type electromagnetic brake are provided. An acute triangle voltage wave generation unit generates a stepped acute triangle voltage wave which is formed by valley parts with a first angle and peak parts with a second angle smaller than the first angle arranged alternatively. A comparative voltage wave generation unit generates a comparative voltage wave based on current which flows through the brake coil. A comparison unit compares the acute the triangle voltage wave with the comparative voltage wave when the non-excited operation type electromagnetic brake is in the holding state. A switch performs switching to supply current to the brake coil when the acute triangle voltage wave is larger than the comparative voltage wave and to cut off the supply of current to the brake coil when the actute triangle voltage wave is not larger than the comparative voltage wave.

摘要： A control device for a hoist, which enables easy judgment of the lifetime of a brake of a hoist is provided. The time setting unit sets the time from startup of a double winding induction motor to disengagement of the brake and the time from start of engagement of the brake to stopping of the double winding induction motor in accordance with the time from the startup of the double winding induction motor to generation of torque. The time changing unit detects if power-supply frequency of a power supply is 50 Hz or 60 Hz and can change at least one of the time from the startup of the double winding induction motor to the disengagement of the brake and the time from stopping of driving of the brake to stopping of double winding induction motor in accordance with the power-supply frequency of the power supply.
