Abstract
Gas-engine replacement devices described herein include a housing that includes battery receptacle configured to removably receive a battery pack, a motor located within the housing, a power take-off shaft receiving torque from the motor and protruding from a side of the housing, a power switching network configured to selectively provide power from the battery pack to the motor, and an electronic processor. The electronic processor is coupled to the power switching network and configured to receive a current measurement associated with the motor and control the power switching network according to one of a freewheeling mode or a synchronous rectification mode based on the current measurement.
