Control device of diving explosion suppression permanent magnet brushless direct current motor used in explosion-proof propeller

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.

Description

technical field [0001] The invention discloses a submersible explosion-proof permanent magnet brushless DC motor control device for an explosion-proof thruster, which belongs to the technical field of propulsion devices for coal mine ships and relates to a permanent magnet brushless DC motor and a control device thereof. Background technique [0002] Traditional propulsion devices for boats usually use gasoline engines, diesel engines, and electric motors, which can be used in rubber boats for water play, flood control and disaster relief, and patrol and duty. , Gas and other flammable and explosive gases, sewage media and other environmental conditions limit, ordinary internal combustion engines or electric motors and other conventional power cannot be used, and the rescue boats can only be pushed forward by manual paddling, which is slow and inefficient. At the same time, traditional boats The control device with the propeller cannot meet the requirements for use in coal m...
