Wireless remote control can achieve the charged objectives by the method of non-contact remote control and they are widely used in industrial control, aerospace, the field of home appliances. Compared with the cable and infrared equipment, wireless remote control and wireless transmission system improves the degree of freedom of movement, thus making the wireless remote control devices and wireless transmission system is more and more used in the industrial field. Compared with the cable to connect, it has a lower cost of installation (no wiring, no underground works, no cable trough), and increase the flexibility but reduce maintenance cost. In the control of a remote control car, in addition to the remote transmission signal control, locomotive and its driving and steering control are also important parts. Only the control is accurate and power steering is adequate, can the locomotive achieve accurate position and can we get accurate response. In order to achieve the driving power is sufficient, we can use the DC brushless motor power density. In order to make accurate steering, we can use the stepper motor control. Brushless DC motor and stepper motor together form the driving force system.Keywords: Remote control cars, brushless DC motor, stepping motor, driving force system目 录摘要..............................................................ⅠAbstract........
