Is it difficult to choose a brushless motor.
I believe that on the path of choosing a brushless motor, there are always obstacles. From the motor model, performance parameters, functional requirements, price comparison, etc., every step does not meet the requirements. You have to re screen the manufacturers and start over. This is an endless cycle and must be done for engineering and procurement in search of motors.
TOPBAND motor, in order to reduce your unnecessary time costs, let me briefly talk about the performance and price requirements of brushless motors. It will be easier for you to find them after screening.
In the field of micro motors, brushless motors are mainly divided into inner rotor brushless motors, outer rotor brushless motors, and hollow cup brushless motors. Brushless motors typically use voltages within 36V, diameters within 70mm, and speeds ranging from several thousand to tens of thousands of revolutions per minute, depending on the specific product requirements.
In terms of price, the price of brushless motors fluctuates greatly, with batch production ranging from 15-300 yuan per unit, depending on the performance of the brushless motor. For example, for high torque or high-speed motors, if the magnets and bearings used are not standardized, better performing sintered magnets and foreign ball bearings are needed as substitutes. In addition, brushless motors usually only have three wires for positive and negative poles and PWM speed regulation, without a drive board. If customers want more demand, they need to add a drive board. The performance and requirements of each drive board are also different, and the cost is gradually increasing.
There are also secondary factors, such as temperature control requirements and the need for external anti-corrosion and rust prevention of the motor, which will increase the process cost of the motor to a certain extent, and naturally the cost of the motor will also rise.
Of course, the final price still depends on the wholesale quantity, such as batch 3K or batch 50K. For the same brushless motor performance, the price range can be reduced by a few cents to several yuan/unit, or even more than ten yuan/unit.
Brushless motor is a motor with high degree of freedom, and each component can be customized according to requirements. However, the more customized content, the higher the cost. Therefore, it is better to use the model already made by the original manufacturer's mold for production, which can greatly reduce the cost and production time to a certain extent.
