How to choose between AC and DC motors?

The construction of these two types of engines is different. The most fundamental difference is the power supply: alternating current (single-phase or three-phase) and direct current (DC/DC), such as for batteries. Speed ​​is another sign of differentiation. The speed of a DC motor is controlled by ... read more

What is the reason for the overheating of the motor inverter?

The cause and treatment of the inverter overheating and overloading fault: Phenomenon 1: Overheating: OH is also a common fault. 1. Fan stall: The main cause of the failure: the ambient temperature is too high. The temperature sensor has poor performance and the motor is overheated. Therefore, the t... read more

What is a motor ?

Electric motors are also called motors (commonly known as motors) and are represented by the letter "M" in the circuit (the old standard uses "D"). Its main function is to generate driving torque as a power source for electrical appliances or small machinery. The motors introduced in this article ar... read more

Which home appliances are permanent magnet DC motors widely used in household appliances?

In the field of household appliances, such as air conditioners, washing machines, refrigerators and other products, permanent magnet synchronous motors or permanent magnet DC motors are gradually replacing the original asynchronous motors. As the price of permanent magnet materials goes down, the co... read more

The working principle and superiority of DC motor

The direction of the conductor's force is determined by the left-hand rule. This pair of electromagnetic forces forms a moment that acts on the armature. This moment is called electromagnetic torque in a rotating electrical machine. The direction of the torque is counterclockwise in an attempt to ma... read more
