The problems in elevator door-motor system and picks up the system scheme which adopts the DC brushless motor to act as drivermotor based on MSP430F149 is analysed.
The working principle of a new double closed-loop thyristor trigger CF6B-2A and its application in the control system of drivermotor in the extruder were introduced.
介绍了双闭环可控硅触发器CF 6 B - 2a的工作原理，并将该器件应用于挤塑机主驱动电动机控制系统中。

In motor racing, for instance, if a driver is taken to hospital after a crash the metal in the capsule would prevent the use of an MRI scanner, which is essentially a powerful magnet.
