Electric-powered lubricant dispenser, and method for dispensing lubricant from electric-powered lubricant dispenser

Abstract

One aspect of the present disclosure provides an electric-powered lubricant dispenser including a motor, a pump, a drive circuit, and control circuit. The pump is (i) driven by the motor and (ii) dispenses a lubricant. The drive circuit drives the motor. The control circuit rotates the motor via the drive circuit. The control circuit performs a specified process based on (i) the motor being driven and (ii) an actual operating amount of the motor satisfying a specified requirement. The actual operating amount indicates an actual rotational speed of the motor or a magnitude of fluctuation in the actual rotational speed. The specified requirement is a requirement indicating that gas is present in the pump.
