What are the common parameters of brushless DC micromotors

In addition to brushed motors, brushless DC micro-motors are more common micro-motors, no brush device, reducing friction, reducing noise, greatly increasing the service life. But brushless DC micromotors compared to brushed motors, the price will be slightly more expensive, more applications in the model airplane products. So what are the common parameters of brushless DC micromotors?

Brushless micro DC motor parameters.

1. rated voltage: that is, the operating voltage applicable to the micro motor, micro motors have many suitable operating voltages, rated voltage is obtained by specifying the load conditions.

2. KV value: the rated speed of the micro brushless motor is marked according to the rated working voltage, brushless motor KV value, which is to let intuitively know the speed of the micro brushless motor at a specific working voltage (actual speed = KV value working voltage).

3. torque: the driving torque generated by the rotor of the micro-motor that can be used to drive a mechanical load, i.e. the rotational force of the micro-motor.

4. rotational speed: i.e. the rotational speed per minute of the micro-motor.

5. upper limit current: the upper limit current that the micro-motor can withstand and work safely.

6. upper limit power: the upper limit power that the micro-motor can withstand and work safely (power = voltage and current).

These are the common parameters of brushless DC micromotors, understand the basic working principle of brushless motors and master these parameters in order to better use brushless motors.
