Research on soft start mode of grading discrete frequency conversion for mine asynchronous motor
In view of problem that traditional soft start mode of mine-used asynchronous motor has big starting current, small starting torque, and cannot achieve overload or full load start, voltage regulation circuit and protection circuit were improved based on existing grading discrete frequency conversion...
