Dual-closed loop structure is adopted in main thrust motor and rudder motors, and PI controller is implemented by DSP software.

对主推进电机和舵电机的控制采用了双闭环结构，PI调节器由DSP软件实现。

In order to satisfy the operation requirement of the rated thrust of the propeller, the propulsion motor performs only in rated torque on the low speed, so the motor power is low.

认为以满足螺旋桨额定推力为目的，推进电动机只需要低速输出额定转矩来实现，即输出功率较低。

In the instantaneous thrust measurement of an attitude control solid rocket motor, dynamic characteristic of thrust measurement system affects the accuracy of thrust measurement.

在姿控发动机的瞬态推力测量中，推力测量系统的动态特性是影响推力准确测量的一个至关重要的因素。

Where a C-class motor from Estes puts out the equivalent of 2 pounds of thrust for one second, an H-class motor--the entry point to high-power rocketry--puts out 55 pounds.
