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

The performance of DC motor is closely related to its excitation mode, usually the excitation mode of DC motor is4Dc separately excited motor, DC shunt excited motor, DC series excited motor and DC compound excited motor. Rotational speednWith torqueTChanging charactern=f(T)Called mechanical properties. It is an important basis for the selection of motor. All kinds of motors are suitable for different occasions because of their own mechanical characteristics.
The characteristic type of DC motor can be selected according to the following circumstances:
(1) Constant torque production machinery(TLDefinitely. It has nothing to do with RPM)To choose the hard characteristics of the motor, such as: metal processing, lifting machinery, etc [3] .
(2) Ventilation mechanical load, mechanical load TL Sum speed n Is directly proportional to the square of. This kind of machinery should also choose the hard characteristics of the motor drive.
(3) Constant power load (P At a certain time,Tandn Inversely proportional), to choose Soft characteristics motor drive. Such as: electric locomotive, etc.

Long axis torque motor products, suitable for winding and winding scenarios, can be customized for different industry scenarios, to meet the requirements of use. This product produced by Senli has the characteristics of reasonable structure, high efficiency, good characteristics and long service life.
Shengzhou Senli Motor19Old motor manufacturers, with a number of their own motor production lines, from the shell, shaft, rotor, stator are independent production, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports. From the shaft machining to the whole machine assembly are completed independently. Truly realize factory direct sales.
Senli motor products are used180°High temperature resistance all copper coil material, torque motor products can be used with different rotors (ordinary rotors/Steel rotor), rotor of different motor characteristics are different, we from the shell, shaft, rotor, stator are produced by the independent, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports.
