What are the basic structures of ceiling fans? What is the difference between its electric motor str

The structure of the ceiling fan consists of four parts: suspension device, machine head, fan blades and speed switch.

There are two main differences between a ceiling fan motor and a table fan motor:

1. Rotational speed. The ceiling fan has a large number of poles and a slow rotation speed; The table fan rotates fast.

Due to the large diameter of the fan blade of the ceiling fan, the speed of the motor cannot be too high, otherwise the linear speed of the blade edge.

Too large, prone to danger, the speed of the motor is usually 300 400r min.

Most of the motors used for table fans use single-phase capacitors to run the motor, and the input power is 32 85W.

2. Rotor and stator.

Ceiling fans belong to the stator rotation type. The stator is installed inside and connected with the boom to fix it, while the rotor is sleeved on the outside of the stator, and the fan blades are directly fixed on the end cover of the machine head. After powering on, the fan blades, upper cover, lower cover, and rotor run together.

The table fans are all stator with coils, which are fixed, and the rotor is a cast aluminum rat dragon coil, which is rotating.

Ceiling fans are basically asynchronous motors, but they belong to the stator rotation type, and the general motors, including the motors of electric fans, are stator with coils, fixed, the rotor is a cast aluminum rat dragon coil, it is rotating, the ceiling fan is the opposite, the stator is with a coil, and the rotor is a cast aluminum strip that rotates with the shell.

The basic structure of the ceiling fan is an external rotor, and an inner stator embedded wire winding; Generally, the structure of the motor (including the table fan) is an inner rotor and an outer stator embedded wire winding.

The ceiling fan is mainly composed of fan blades, fan heads, suspension devices (including booms, lifting climbs and upper and lower covers) and independently installed governors (as required). The structure of the ceiling fan hall fan head 1-rotating shaft; 2-Upper Chana bearing defeated and returned; 3-upper cover; 4-stator; 5-an external rotor; 6-lower cover; 7-Lower bearing Hope it can help you.

Ceiling fans are basically asynchronous motors, but they belong to the stator rotation type, and the general motors, including the motors of electric fans, are stator with coils, fixed, the rotor is a cast aluminum rat dragon coil, it is rotating, the ceiling fan is the opposite, the stator is with a coil, and the rotor is a cast aluminum strip that rotates with the shell.

There are two main kinds of ceiling fans, one is the ceiling fan with a larger capacity that can regulate the speed, its working principle is the working principle of a single-phase asynchronous motor, but the squirrel cage rotor is wrapped around the stator embedded with two-phase windings, because the single-phase power supply can not produce a rotating magnetic field, so one of the windings must be connected in series with capacitors to achieve the purpose of phase splitting.

The other is the breeze ceiling fan, which works on the principle of a synchronous motor that is excited by a permanent magnet, because the synchronous motor is more difficult to start, so a spring must be used to help it start.

The structure of the ceiling fan is: hanging (upper and lower structure) fan (semi-enclosed structure).

The household ceiling fan motor belongs to a single-phase motor, and the industrial ceiling fan motor part is a three-phase motor. The electric fan is a single-phase AC motor, which uses the capacitance to shift the phase to obtain a rotating magnetic field, so that the motor rotates and drives the fan blades to rotate to generate wind.

Inductor speed regulation, i.e., different inductances of core inductors connected in series in the motor circuit. It is a series inductor [the governor is a multi-tap Nakusaka sense] to change the current through the motor.

When the current becomes smaller, the generated magnetic field weakens, and the force on the rotor wire is smaller, and the rotor rotates slowly. This includes external inductors and different taps that utilize the main coil of the motor.

The principle is: because the frequency of the power supply is fixed (50Hz), and the more pairs of stator poles of the motor when the motor is working, the slower the speed, so by changing the number of pole pairs of the stator when the motor is working, the speed of the rotor can be changed.

Single-phase asynchronous motor positive and negative**

Let the current flowing through the main winding be ia, and the current flowing through the secondary winding of Changpai is ib. In general, the number of turns of the working winding is large, the inductance is large, and it is an inductive load, so the IA lags the power supply voltage in phase.
