Dongguan RC brushless dc motor to choose more cost-effective
small dc motor is usually no. 11 frame, each frame, there are two core length, suitable for use in a normal working environment, today for everyone to share the performance characteristics of small dc motor
small dc motor
1. Weakening magnetic field up speed as the constant power running, the dongguan brushless dc motor, but speed shall not exceed the highest speed of the motor is allowed to mechanical strength.
2. Reduce the armature voltage down speed:
1) separately excited motor speed adjustment before down, should be weakening magnetic field up to the specified value (The general is 1. 2 times the rated speed)After decompression speed down.
(2) by ventilation cooling down the motor speed control for constant torque operation.
3. Since the fan cooled motor torque will reduce decreases with the rotating speed.
ventilation mode since the fan cooled (Bring their own fans, axial ventilation)And his fan cooled (Built-in fan, dc brushless motor, forced ventilation), also don't take fan, according to the ventilation pipe type to use.
so how are the structure of small dc motor?
1. Brushless dc motor and the dc generator voltage regulator in horizontal, only stand with a foot.
2. The structure of the dc motor can be made in the following table is shown in model.
