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 a 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 a load torque satisfying a first requirement during driving of the motor. The load torque is (i) applied to the motor from outside the motor and (ii) generated based on a load received from the pump. The first requirement is a requirement corresponding to a state in which gas is present in the pump.
