Abstract

The invention discloses a control device of a diving explosion suppression permanent magnet brushless direct current motor used in an explosion-proof propeller, which belongs to the field of a coal mine boat-used propulsion device technology, relating to a permanent magnet brushless direct current motor and a control device thereof. The technical problem to be solved is to provide a control device of a diving explosion suppression permanent magnet brushless direct current motor of a boat-used propeller which can be used in underground coal mines. The adopted technical solution is that: an input end of an IPM inverter unit is connected to a low voltage direct current power, an output end of the IPM inverter unit is connected to the diving explosion suppression permanent magnet brushless direct current motor, a drive end of the IPM inverter unit is connected to a drive and protection module, and a control end of the IPM inverter unit is connected to a DSP control module; and the DSP control module is connected to the drive and protection module and a signal detecting module separately, and an input end of the signal detecting module is connected to a signal output end of a three-phase Hall sensor and a signal output end of a voltage current sensor separately. The control device of a diving explosion suppression permanent magnet brushless direct current motor provided by the invention is applied to rescue boats used in underground coal mines.
