Abstract
A motor assembly includes a motor, a control circuit to generate a control signal, a motor driving circuit to cause a current to flow in the motor based on the control signal, a storage to store a first identifier uniquely identifying itself and a second identifier uniquely identifying another motor assembly within the communications network, and a communication circuit. The communication circuit transmits a data frame, in which the first identifier indicates a transmitting end, the second identifier indicates a receiving end, and a request are stored. The communication circuit receives from the other motor assembly a data frame including the second identifier indicating a transmitting end, the first identifier indicating a receiving end, and a request. In response the communication circuit transmits a data frame including the second identifier indicating a receiving end added thereto and the first identifier indicating a transmitting end added thereto.
