锥形电机的工作原理为：定子内腔和转子外圆均为圆锥形，当电机通电时，作用于转子上的磁拉力分解为径向力和轴向力，由于轴向力的作用，使电机转子产生轴向移动，压缩制动弹簧，使风扇制动轮离开制动器座的锥面，失去制动作用，使电机开始旋转。电机断电，轴向力消失，制动器复位，使电机制停。
The working principle of the conical motor is that the stator cavity and the outer circle of the rotor are conical. When the motor is electrified, the magnetic pull force acting on the rotor is decomposed into beijing.89ix.com zhixiang.07858.netdianxiangan.37ix.cn zhoucheng.37ix.cn chongdianzhuang.07858.net langyashan.37ix.com.cnradial force and axial force. Because of the action of the axial force, the rotor of the motor moves axially, and the brake spring is compressed, so that the fan brake wheel leaves the conical surface of the brake seat, loses its braking effect and the motor begins to rotate. When the motor is cut off, the axial force disappears, and the brake is reset, which makes the motor stop.
锥形电机在安全方面比普通三相异步电机的刹车性能提高，采用机械刹车原理，相对电气刹车更加可靠。
The braking performance of conical motor is better than that of ordinary three-phase asynchronous motor in safety. The mechanical braking principle is adopted, which is more reliable than electric braking.
