摘要： The disclosed invention is a dispensing apparatus and method for dispensing product from a vending machine. The invention employs a motor for bi-directionally rotating a dispenser bucket between two bumpers which physically obstruct and limit the rotational travel, a motor controller for monitoring the current drawn by the motor and signals received from a product vend detection sensor. The motor controller uses monitored information to control the rotational direction and stopping positions of the dispenser bucket. The invention eliminates the need for timing cams and switches and eliminates the need for anti-theft device to prevent product theft from the dispenser bucket.
