12V Brushless DC Motor BLDC Motor Customized Specification With Controller For Smart Home Appliance
| Rated voltage | 12VDC |
| Rated speed(free load) | 1800+/- 10% RPM |
| Rated current(free load) | 4.5W max |
| Rated load | 69.5mN.m |
| Rated speed(on load) | 1800+/- 10% RPM |
| Rated current(on load) | 18W max |
| Insulation resistance | 10MΩmin. (500VDC) |
| Dielectric strength | 600VAC/1S leakage current <=5mA |
| Temperature rise | <60K |
The motor drive is DC chord vector control, and its characteristics are shown in the following table:
| Input voltage | 100-255VAC |
| Input power | 20W |
| Output voltage | 12VDC |
| Output power | 18W max |
| Control method | PWM input |
| Position detection method | FOC |
| Soft start function |
After the controller is powered on, the motor is slowly accelerated to the required value after starting. |
| FG signal |  |
| PWM signal |
PWM frequency range: 15-28KHz Duty cycle range: 1%~99% L level: 0-1.0V; H level: 2-5.5V |
| Locked rotor protection | When the load brought by the motor encounters great resistance from the outside to stop the motor, the controller temporarily stops the motor. After a few seconds, the motor tries to start. If the resistance is absent, the motor runs normally. If the resistance is still present, the motor stops temporarily again. After several cycles, the motor stops. Manually remove the resistance, and press again to start the motor. |
| Open phase protection |
When one or two of the three phases of the motor are not energized, the motor stops running. |
| Over current protection | If the motor current suddenly increases beyond the set value due to external factors, the motor will stop running. |
| Rated voltage | 12VDC |
| Operating voltage | 10.8 - 13.2 VDC |
| Rotation direction | CW |
| Working duty | continuous |
| Operating condition | 0℃~120℃, RH 5%~90% |
| Storage condition | -20℃~60℃, RH 5%~90% |
This is one type of brushless DC motor.
Brushless DC motor uses electronic communtation instead of mechanical steering. Compared with Brush DC motor, it has long working life and eliminates mechanical steering's noise, sparks and electromagnetic interference and so on. It is of great convenience and reasoning to control motor's performance. Brushless DC motor can be mainly divided into two parts, motor and circuit control. Motor is composed of rotor which its main component is permanent magnet and of stator which its main component is silicon steel sheet and copper wire.
