Does a brushless DC motor belong to a power motor or a control motor?

Today, a customer asked us if our DC brushless motor is a power motor or a control motor. Before answering this question, let's first explain what power motors and control motors are.

Power motors, as the name suggests, are motors that provide power and are commonly used in electric vehicles and buses. They are very high-power motors, often reaching several kilowatts, and they are also brushless motors. The main function of controlling motors is to control, such as servo motors, speed generators, self aligning machines, rotary transformers, and stepper motors. They can achieve very precise control, with a control accuracy of up to 0.01mm or 00.1 °/S, and a speed accuracy of+/-0.1 °. They are mostly used in products with high precision requirements such as camera gimbals, correction control systems, textile machines, etc.

A brushless motor with constant drive can provide micro power, such as being used in a fan to convert electrical energy into kinetic energy and rotate the blades; It can also provide control, such as PWM speed regulation function and FG signal feedback output, which can read the speed according to the signal and change the speed according to the signal. Due to size limitations, constant drive brushless motors do not provide much power, so they are often used in small household appliances and product components, such as curling irons and car wipers; In terms of control, the brushless motor of the constant drive includes three Hall sensors, which can control an angle of 60 degrees. If more precise control is required, an encoder needs to be equipped.

After understanding the above characteristics, we believe that customers can better choose products that are suitable for themselves.
