A brief evaluation of table fan motors

A table fan motor is a motor with a fan hub and blades. The table fan motor has evenly distributed slots along the outer circumference of the fan hub. The blades are inserted into the slots. The table fan motor is permanently connected by welding, bonding, and other methods to make the blades. Integrate with the fan hub. The overall balance of the table fan motor is good, which can save the man-hours required to adjust the balance, and the weight is more than 30% less than that of the bolt-connected fan. When the table fan motor adopts the motor of the utility model, the vibration and noise during operation are reduced.

Introduction to table fan motors

Although the table fan motor has high reliability, the table fan motor is still a mechanical device. When used for a long time, the speed of the table fan motor may drop or even stop. Therefore, it is best to monitor the running status of the table fan motor in real time, It is convenient to find the problem in time. The alarm sensor can be used to give an alarm signal when the speed of the table fan motor is lower than a certain threshold, and the speed signal output can realize real-time monitoring of the speed of the table fan motor. The alarm signal output from the table fan motor circuit is "high voltage". There are two states of "level" and "low level". The meanings represented by the two levels are generally in accordance with the positive logic system. High level means "fault" and "low level" means "normal". The rotation speed signal output from the table fan motor circuit is usually in the form of pulses, and each wave head indicates that the fan has rotated one circle. Such signals can be directly provided to the host through the data bus for display. The speed signal output by some table fan motors is not the true speed of the table fan motor, but a multiple of the speed. For example, every revolution generates 2, 4, or 6 pulses, which must be processed to form a reflection of the table fan motor. Real speed signal. If you want to distinguish whether the rotation speed of the table fan motor is the real rotation speed or a certain multiple, you can use the tachometer to measure the actual rotation speed, and then compare it with the displayed data. The speed measurement signal of a table fan motor is generally output from a three-lead plug. The yellow and black of the three leads are +12V power and ground respectively, and the other color line is the speed signal output line. It should be noted that the third lead of some three-lead fans is not a speed measurement signal output line, but a speed control signal line, through which the speed control signal is input to the table fan motor.

Specifications of table fan motors

Table fan motor blades are distinguished by the frame number of the motor, such as Y series: 80, 90, 100, 112, 132, 160, 180, 200, 225, 250, 280, etc.

It is the responsibility of each manufacturer to produce table fan motors that meet the standards to ensure the healthy development of the table fan motor market. Before leaving the factory, the Guangzhou Yuexun Electric Appliance Co., Ltd. has conducted a large number of connection tests on the table fan motors, and the quality assurance rate is guaranteed. If you are in the business of table fan motors, you can consider using our cost-effective products.
