The invention belongs to the technical field of motor preparation, and particularly relates to an electromagnetic direct-acting type speed change and torque conversion device which comprises an inputshaft, a sun gear, a planet gear, a gear ring, a planet carrier, an electromagnetic direct-acting type clutch, an electromagnetic direct-acting type brake, an output shaft, a front disc, a front disccover, a shell, a rear disc and a rear disc cover. According to the electromagnetic direct-acting type speed change and torque conversion device, under the condition that the rated power of a single motor and an electric control dragging system are not changed, the rated rotating speed and torque output of an original motor can be converted, that is to say, two different rated rotating speeds andtorque outputs can be achieved under the condition that the rated power of the single motor is not changed; generally, a 1:1 gear is used for operation, the motor economically operates at a high rotating speed and a low torque, and under the condition of full load or overload, a 1/(1+Z4/Z2) times (speed reduction) gear and a torque (1+Z4/Z2) times (torque increase) gear are used, and the motor operates at a low rotating speed and a large torque; and under the two conditions, the motor outputs at rated power, the consumption of reactive power is reduced, and the loss of electric energy is reduced.

    本发明属于电机制备技术领域,具体为电磁直动式变速变矩装置,包括包括输入轴、太阳轮、行星轮、齿圈、行星架、电磁直动式离合器、电磁直动式制动器、输出轴、前盘、前盘盖、壳体、后盘、后盘盖。本发明为了实现单台电机在额定功率及电控拖动系统不变的情况下,使用本电磁直动式变速变矩装置,使原有电机可以变换额定转速及转矩输出,也就是单电机额定功率不变的情况下可以有二种不同额定转速及转矩输出;通常的情况下,运行使用1:1档,电机在高转速低转矩经济运行,当在满载或过载的情况下,使用转速1/(1+Z4/Z2)倍(减速)及转矩(1+Z4/Z2)倍(增矩)档,电机在低转速大转矩运行;这二种情况下,电机都是在额定功率输出,降低无功功率的消耗,减少电能的损失。
