CONTROLLER BY BATTERY DRIVE FOR MOTOR DRIVEN TOOL

摘要

PURPOSE:To operate in an arbitrary torque/rotating speed characteristic set in advance by controlling an MOSFET by the output of a microprocessor which inputs the outputs of a current detecting resistor, a rotating speed setter and a torque setter. CONSTITUTION:A microprocessor 17 inputs the outputs from a current detecting resistor 14, a rotating speed setter 15 and a torque setter 16, and applied an output corresponding to the preset torque/rotating speed characteristic to the gate of an MOSFET13. Thus, suitable torque/rotating speed characteristic adapted for the request of a load can be readily obtained.
