Description

Technical field: [0001] The invention relates to a torque motor speed regulating device, in particular to a device whose speed can be stably and continuously adjusted within a wide range from zero to thousands of revolutions without a decelerating mechanism. Background technique: [0002] In the speed adjustment device, torque motor speed regulation is often encountered in many mechanical equipment and weaponry, such as the rotation of the mechanical arm, the rotary motion of the processing equipment, the transmission of the workpiece in the automatic production line, the search of the radar antenna, the aiming of the artillery Wait. In the torque motor speed control device, the adjusted variable is the movement speed of the mechanical load. In order to obtain the operating speed with lower mechanical load, a reduction device must be arranged between the torque motor and the mechanical load. In this way, not only the cost of the speed regulating device is increased, but al...
