When the equipment uses a miniature geared motor, there will be an overload situation, and sometimes a similar overload problem will occur. Most people don't know what overload means. If you read the following four reasons, you will know:
1. The power supply voltage is too low: the miniature geared motor is operated under the standard of more rated current, and the current in the stator winding increases more, causing the stator winding temperature to increase more and over-temperature burns.
2. Poor selection of the miniature geared motor model: the load working condition standard of the specific application is not matched with the method of selecting the submersible sewage pump; it is too high or too low.
3. Common reflective faults: the rolling bearings of the miniature reduction motor are seriously damaged, the stator and the motor rotor are rubbed "sweeping" or the water pump is stuck by various plants and other dirt, and other common reflective faults are caused by the stator windings of the miniature reduction motor. burn.
4. Quality factors in the manufacturer or maintenance: the quality of the manufacturer's Wanjia maintenance causes the submersible sewage pump to overload.
After understanding the four major causes of overload of miniature geared motors, the four major causes cause this problem in miniature geared motors. If such a problem occurs in the future, it can be distinguished based on the situation at which point the problem is caused.
There are many types of miniature reduction motors. The motors that make up the motors can be divided into the following five types: single-phase electromagnetic induction motors, reversible motors, electromagnetic brake motors, variable-speed motors, and three-phase motors. These five types often have different characteristics and main uses. They must be used in many places. Let's look at the actual detailed introduction of the Haoshun motor manufacturer:
1. Single-phase electromagnetic induction motor
Capacitive magnetic induction motors can be applied consecutively, with high power and low noise.
2. Reversible motor
It is basically not easy to switch to a conversion prohibition condition with a momentary conversion of forward and reverse. Due to the selection of the balanced winding method and the simple brake system organization of the inner window. It can change forward and reverse in an instant.
3. Electromagnetic brake motor
The brake pedal can be braked in a short period of time, and when there is no load, the brake pedal can be used for 2 to 3 turns, giving full play to the characteristics of the safe brake pedal.
Four, variable speed motor
The interoperable speed control board has a wide range of variable speed coverage: 90~1400RPM. The internal speed sensor is always available, and feedback adjustment is implemented. Therefore, the switching power supply frequency has a change, and the required speed must not change.
Five, three-phase motor DC motor
With the addition of a soft starter, the speed of the three-phase motor can be adjusted; the speed of the brushless DC motor can be adjusted by changing the working voltage connected to the power supply to maintain the variable speed effect.
