The difference between Chenggang DC and Chenggang DC reducer

The difference between Chenggang DC and Chenggang DC reducer The ordinary DC motor generally has a higher speed and a smaller torque, which is suitable for occasions with less torque requirements.

The DC geared motor, that is, the geared motor, is based on the ordinary DC motor and is equipped with a gear reducer. The role of the gear reducer is to provide a lower speed and a larger torque. At the same time, the different reduction ratios of the gearbox can provide different speeds and torques. This greatly increases the use of DC motors in the automation industry.

1. According to the type of working power: can be divided into DC motor and AC motor.

1.1 DC motor can be divided according to structure and working principle: brushless DC motor and brushed DC motor.

1.1.1 Brushed DC motor can be divided: permanent magnet DC motor and electromagnetic DC motor.

1.1.1.1 Electromagnetic DC motor division: series-excited DC motor, parallel-excited DC motor, separately excited DC motor and compound-excited DC motor.

1.1.1.2 Permanent magnet DC motor division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and AlNiCo permanent magnet DC motor.

1.2 Among them, AC motors can also be divided into: single-phase motors and three-phase motors.

2. According to the structure and working principle: can be divided into DC motor, asynchronous motor, synchronous motor.

2.1 Synchronous motor can be divided: permanent magnet synchronous motor, reluctance synchronous motor and hysteresis synchronous motor.

2.2 Asynchronous motors can be divided: induction motors and AC commutator motors.

2.2.1 Induction motors can be divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded-pole asynchronous motors.

2.2.2 AC commutator motor can be divided: single-phase series-excited motor, AC-DC motor and repeller motor.

3. According to the starting and running modes: capacitor-starting single-phase asynchronous motor, capacitor-operated single-phase asynchronous motor, capacitor-starting single-phase asynchronous motor and split-phase single-phase asynchronous motor.

4. Divided by purpose: drive motor and control motor.

4.1 Drive motor division: electric tools (including drilling, polishing, polishing, grooving, cutting, reaming, etc.) with electric motors, household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVDs) Motors, vacuum cleaners, cameras, hair dryers, electric shavers, etc.) Motors for motors and other general purpose small mechanical equipment (including various small machine tools, small machines, medical equipment, electronic equipment, etc.).

4.2 Control motor is divided into: stepper motor and servo motor.

5. According to the structure of the rotor: cage induction motor (the old standard is called squirrel cage asynchronous motor) and wound rotor induction motor (the old standard is called wound asynchronous motor).

6. According to the operating speed: high-speed motor, low-speed motor, constant speed motor, speed control motor. Low-speed motors are further classified into gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors.

In addition to the stepless constant speed motor, the stepless constant speed motor, the stepless variable speed motor and the stepless variable speed motor, the speed regulating motor can also be divided into an electromagnetic speed regulating motor, a DC speed regulating motor, a PWM variable frequency speed regulating motor and Switched reluctance motor.

The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field.

The rotor speed of the synchronous motor is always kept at the synchronous speed regardless of the load.
