Three common types of brushless motors

Brushless motors can be divided into three different types according to different position sensors. When using different types of products, we also need to make appropriate choices according to different situations. From the type point of view, it can be divided into magnetic sensitive type, photoelectric type and electromagnetic type.

Magnetic brushless motor

This type of product mainly installs some magnetic sensitive sensors on the battery components, so that it can effectively detect the changes in the magnetic field generated by the rotation of the magnet and the rotor. A place looking for value for money.

Photoelectric brushless motor

This type of brushless motor is mainly to install corresponding photoelectric sensor devices on the electronic components, to display correspondingly through small light bulbs or diodes, and to control intermittently through pulse signals generated by photosensitive components.

Electromagnetic brushless motor

Electromagnetic brushless motor, this is to install the corresponding battery sensor parts on the battery assembly, so when the rotor of the permanent magnet changes, these parts will generate corresponding high-frequency tuning signals, through his changes can be more A good representation of the rotor position, which drives the motor to run.

How to choose the three common types of brushless motors?

Only by choosing the right product can everyone obtain comprehensive and effective functions in the application of brushless motors, and truly implement them in practice. Therefore, when choosing a variety of brushless motor products in the market, everyone must first distinguish which type it is. Through the difference in position sensors, the principle of the equipment will also have a little difference in the use of the environment. And the functional characteristics presented in the work will also be different. You need to figure this out in order to ensure that you can get a more satisfactory feeling in the selection and use of products.

Several points to pay attention to when purchasing DC brushless motors

Because of its low noise, small weight and long service life, DC brushless motors are widely used in the automotive industry and medical industry. However, motors also have different specifications and types. When purchasing, you should consider the specific situation and pay attention to whether the price is reasonable. So how to choose a suitable motor?

Specification comparison

Because the adjustment of the power supply voltage can directly affect the speed of the motor, etc., then we also need to choose a motor with suitable torque and speed according to actual needs, so as to determine the specifications of the DC brushless motors. In fact, even if the power supply voltage is fixed, you can also choose a DC brushless motor. You only need to choose according to the specifications and parameters, so that the subsequent use is also guaranteed.

Power comparison

Each motor has a different type of power and has a corresponding power limit. If the power is selected to be relatively small, then after the load is exceeded, problems such as motor heating, speed drop, and abnormal noise will definitely occur, which will further damage the motor and cause the motor to burn out. However, if the power is too large, the price will be higher, which is not cost-effective, so it is necessary to choose a motor with appropriate power according to actual needs.

Brand comparison

There are many different types of DC brushless motors launched by regular brands, and the models, parameters, and functions are also different. If you want to choose a suitable motor, you must pay special attention to which brand is better and meets our needs. You can directly cooperate with the manufacturer. The motors sold on the brand's official website are of guaranteed quality, with various models, and the price/performance ratio is also good.
