DCB Brushless DC Series Motors

Overview

With all the functionality included into the design of this BLDC motor it is versatile yet strong enough to operate in many applications.

1. Operating voltage range: 8-26VDC.

2. Motor axial end play: 0.05-0.5mm.

3. Measuring method for motor output shaft extension: push the rotor against the end cap to measure the shaft extension.

4. Cable connection method:

4:1 When the red wire is connected to the positive pole if the power supply (+) and the black and blue wire are connected to the negative pole of the power supply (-) the motor direction is CW when viewed output shaft side of the motor.

4:2 When the red wire is connected to the positive pole if the power supply (+) and the black, blue and yellow wire are connected to the negative pole of the power supply (-) the motor direction is CCW when viewed output shaft side of the motor.

4:3 When the blue wire is connected to the (-) the motor runs at full speed. When the blue wire is connected to the PWM signal the speed can be adjusted.

4:4 The cable connection method of the motor must comply with the above instructions. Reverse connection of the positive and negative of the power is strictly forbidden. Do not connect the voltage higher than 26VDC.

4:5 When connecting the terminal with the motor connector, the terminal should be aligned accurately and inserted slowly. Force pressed is forbidden. When separating the terminal from the motor connector do not pull the lead wires by force to avoid possible damage to the motor connector.

5. If pressing any part onto the motor shaft the other shaft end must be supported as the spacer ring or bush/bearing inside the motor could be damaged due to the thrust force.

6. The maximum length for fixing screws into the motor housing is 3mm.

7. Motor complies with RoHS.
