Variable speed multi-tap brushless DC motor using wireless technology

The brushless dc motors are widely used in the servo motor application because of their advantages over conventional DC motors. In this paper, the motor is operated remotely using wireless technology and thereby reduces labour cost, maintenance cost and improves ease of operation. Speed control of BLDC motor is quite complicated. A novel tapped field open loop control method using wireless technology is proposed in this paper. Many applications such as heating and ventilation, industrial engineering, transport, motion control systems, radio control cars etc can be more efficient using this method.
