A micro-motor is a motor with a diameter of less than 160mm or a rated power of less than 750W. Micromotors are commonly used in control systems or transmission mechanical loads for the detection, resolution, amplification, execution or conversion of mechanical and electrical signals or energy.

Answer: Motor factory often receive from different customer to consult custom non-standard motor demand. Because the understanding degree of micro-motor and industry product is different, the customer will have a lot of problems in communication with the manufacturer. In order to help everybody to communicate more efficiently with the manufacturer, we sum up the following points of attention:

1. Explain to the manufacturer the main specifications parameter requirements of the customized motor, such as motor diameter, length, shaft diameter, voltage, speed and other basic information. If there are drawings or parameter table, it can be directly sent to the manufacturer. The engineer can quickly confirm whether it can be done or not after getting the preliminary evaluation of these data.

2. Inform the motor factory of the specific application of the motor, that is, the motor is to use on what products, to do what action, working environment and so on. These information can help engineers in their own technical library to search the application of the motor program in the industry, which can speed up the progress of technical evaluation. 

3. Inform the manufacturer of the expected demand quantity of the motor. The confirmation time of motor customization is long (especially for that is needed to open new molds). There are many processes, so the manufacturer has some requirement to the custom item quantity. If the quantity demanded is small, we will inform the customer that there is no need to customize.

4. If there is a complete project schedule, it’s better to share it. There must be a lot of customized projects in the motor factory. In the face of different requirements from different customers, if we have this schedule, the engineer can arrange the opening time, material period, first sample time, experimental period, customer installation test, small batch trial production and so on in advance to match the customer’s project schedule.

1. Long life: Brushless motor uses electronic commutator instead of mechanical commutator. There is no brush and commutator friction. The life is several times higher than brush motor. 

2. Small interference: The brushless motor removes the brush and has no electric spark, which reduces the interference to other electronic equipments. 

3. Low noise: Because of its simple structure of DC brushless motor, spare and accessory parts can be precisely installed. The running is relatively smooth with running sound under 50db. 

4. High rotation: There is no brush and commutator friction for brushless motor. The rotation can be higher
