REVERSING DISPENSER MOTOR WITH INTEGRAL RELAY

摘要

A dispensing motor apparatus includes a motor assembly for driving a dispenser, the motor assembly having a motor. The dispenser is driven by the motor. One or more relays having electrical contacts can be integrated with the motor assembly. The motor changes its direction of rotation when its polarity is switched by relay(s). Additionally, a controller can communicate with the relay(s) and the motor assembly, such that the controller permits the relay(s) to switch the position of the contacts of the relay(s) before power is turned on with respect to the motor through the electrical contacts and switch the position of the electrical contacts of the relay(s) to a default state after the power is removed from the motor through the electrical contacts. The relay(s) is subject to mechanical cycling without the contacts of relay(s) being required to perform a current switching duty.
