Torque motor is characterized by soft mechanical characteristics, is a kind of special motor with soft mechanical characteristics and wide speed range. When the load increases, the speed of the motor can automatically decrease, and the output torque increases to maintain the balance with the load. Torque motor has high locked-rotor moment and small locked-rotor current, and can withstand a certain period of locked-rotor operation.
It has the characteristics of low speed, large torque, strong overload capacity, fast response, good linearity, small torque fluctuation, etc., which can directly drive the load without reducing the transmission gear, thus improving the operating accuracy of the system.
In order to obtain different performance indicators, the motor has three different structural forms of stingy gap, air gap and air gap. The stingy gap structure can meet the requirements of general use accuracy, and the advantage is that the cost is low;
Air gap structure, due to the increase of air gap, disappear-In addition to the slotting effect, the torque fluctuation is reduced, and the nonlinear change of magnetoresistance is basically eliminated. The linearity of the motor is better, the electromagnetic air gap is increased, the armature inductance is small, and the electrical time constant is small, but the manufacturing cost is high.
The performance index of the air gap structure is slightly lower than that of the air gap structure motor, but it is much higher than that of the cheap gap structure motor, and the volume is smaller than that of the air gap structure motor, and the manufacturing cost is lower than that of the air gap structure motor.
