为了提高电动机速度的控制精度,我们将无线电技术中的锁频锁相技术应用到电机中作为速度控制,利用这种技术,可以把电动机的转速锁定于某一特定的频率,只要这特定频率稳定不变,则电动机速度就稳定不变,不受负载、电源等变动的影响,它可以使二个或更多的电机严格地同步旋转,如果基准频率是连续可变的,则电机可以进行宽范围的速度调节,而且速度与频率保持严格的同步。这种稳速电路技术广泛应用于磁带录象机、传真电报机及
In order to improve the control accuracy of the motor speed, we apply the lock-in phase-locked technology in the radio technology to the motor as the speed control, and use this technique to lock the motor speed at a specific frequency as long as the specific frequency is stable Constant, the motor speed is stable, free from load, power and other changes, it can make two or more motors strictly synchronous rotation, if the reference frequency is continuously variable, the motor can be wide Range of speed regulation, and speed and frequency to maintain strict synchronization. This steady-speed circuit technology is widely used in video tape recorders, fax telephones and
