An important element of the normal operation of the ventilator, which can be called the decisive element, is the motor of the ventilator, commonly known as the motor. Motor is an indispensable process in any ventilator. Next, we will introduce the classification of some motors and how to install ventilator motors.
Ventilator motors — Classification
1. According to the type of operation power supply, it can be divided into DC motor and communication motor.
2. According to the structure and operating principle can be distinguished: can be divided into DC motor, asynchronous motor, synchronous motor.
3. According to the starting and working method can be distinguished: capacitive starting single-phase asynchronous motor, capacitive working single-phase asynchronous motor, capacitive starting working single-phase asynchronous motor and split single-phase asynchronous motor.
4. According to the use can be distinguished: drive electric motor and control electric motor.
5. According to the structure of the rotor can be distinguished: cage induction motor (the old specification is called squirrel cage induction motor) and wound rotor induction motor (the old specification is called wound type induction motor).
6. According to the working speed can be distinguished: high speed motor, low speed motor, constant speed motor, speed motor. Low speed motor is divided into gear reduction motor, electromagnetic reduction motor, torque motor and claw pole synchronous motor.
Ventilator motor — device
Turn over the motor shell (do a good job of marking one by one in mind), you will see the blue line is led out by a pay winding lead and a main winding lead, the pay winding lead off the blue line alone lead out of a (new line), now the motor has four lead out, yellow line (new line), red line, blue line lead out, as long as the red. The blue line is exchanged, the series capacitance of the yellow line is unchanged, the blue line merges another capacitor line with one of the power lines, and the red line merges (the new line) with another power line. At this time, the exhaust fan motor is installed.
