The structure of torque motor is circular, which can be divided into rotor motor with the outer ring of the rotor, inner motor with the stator motor, inner motor with the outer ring and inner motor with the rotor. The same size, the external rotor can produce a larger torque, so the external rotor motor is more commonly used.

The main feature of the torque motor is that it has soft mechanical characteristics and can achieve long-term gridlock. When the load torque increases, the speed can be automatically reduced and the output torque can be increased. Here is a simple understanding with Senli Motor Xiaobian.

The DC disc brake of the electromagnetic brake motor is mounted on the end cover of the non-shaft extension end of the motor. When the brake motor is connected to the power supply, the brake will also start to work, the electromagnet will attract the armature and compress the spring due to the effect of electromagnetic suction, the armature end cover and the brake disc will be separated, the motor will start to run; When the power is cut off, the brake electromagnet loses its magnetic attraction, the spring will push the armature, and press the brake disc, and the motor will stop running under the action of friction torque.

Three-phase asynchronous motor can be divided into squirrel cage type and winding type two, the main difference is the structure of the rotor winding, winding asynchronous motor structure is more complex, generally used in starting and speed regulation performance requirements of the occasion, the following and Senforce motor Xiaobian together to understand the next.

Direct current motor is a kind of motor that can convert direct current energy into mechanical energy. Because of its good speed regulation performance, it has been widely used in electric drive. If according to the excitation mode can be divided into permanent magnet, other excitation and self-excitation3Among them, self-excitation is divided into parallel excitation, string excitation and compound excitation3Seed.

Variable frequency motor is mainly used to adjust the working frequency of the equipment, by changing the AC power supply frequency and voltage output to control the corresponding equipment, its application is quite wide, the following Senli motor Xiaobian for everyone to briefly introduce the working principle of variable frequency motor.

The condition for a three-phase asynchronous motor to rotate is to have a rotating magnetic field, and the stator winding in the motor is used to generate a rotating magnetic field. When the voltage between the phase and the phase of the phase power supply is 120 degrees different in phase, and the three windings in the stator are also 120 degrees different in spatial orientation, so that when the three-phase power supply is passed into the stator winding, The stator winding creates a rotating magnetic field.

Brake motor as a power transmission device, and the reducer is different, and is not used as an aid to other machinery, but the brake motor is quite widely used in the transmission field or deceleration field, and its traces can be seen in all kinds of mechanical transmission systems, processing machines and automated production equipment used in the mechanical industry.

Torque motors are often used in the tape supply and take-up motors of tape drives. On such devices, the required voltage is not high, but there is a relatively stable tension on the tape. Torque motors can move forward or rewind quickly without gears and clutches. There are two kinds of DC and AC.
