BLDC Motor Controller (BLMD-2406)
Product Description
The specification of high performance controller
BLMD2406 controller uses dedicated high-performance Brushless DC Motor IC from USA. This controller is suitable for driving brushless dc motors with small and medium power. The motor operates with high speed, small vibration, low noise and stable running due to the new PWM technology

6. Power supply
Normal operating voltage is from 20V to 36V. The driver can be supplied by unregulated DC power. Step-down transformer + bridge rectifier + capacitor filter also. Capacitance can greater than 2200μF. But care should be taken that the rectified voltage ripple peak value is no more than 20V.If you use regulated switching power , note that the output current range of switching power need to be larger than 10A.
Please note: 1.Best to use non-regulated power
2.When using non-regulated power , the output capacity of power current should be higher than 60% current of controller. When using power, the output capacity should be higher than current of controller.
3. In order to reduce the cost, 2 or 3 controllercan share the power. But should improvethe rated power &rated output current of power and pay attention to the heat.
7. Driver Wiring
A complete brushless DC Motor control system should contain a brushless Dc Motor, brushless DC motor controller, DC power and control signals. The following is a typical system diagram
8. Fault Phenomenon and Ruled Out
When the power is on, the emitting tube is with 1-second light and 1-second dark. CW terminal or CCW terminal is with low level. The emitting tube light for long time when the driver operates.
Default phase: emitting tube flare for 2 times and dark for long time-- Check the Hall signal
Restricted rotation or over current: emitting tube flare for 3 times and dark for long time-- Check the Hall signal & Check whether the dead load & Check whether motor with short circuit
