Japan Nedko brushless motor, built-in drive, this motor is 27H series of brushless motor, the torque is much better, this brushless motor can be directly connected to the power supply operation, does not need pwm signal, can run in reverse rotation,This shipment is in bulk and has a few scratches and bumps during transportation.
The actual test voltage of the motor is 9-24v, and even my adjustable power supply test 30v still runs without burning. The white running line of the motor needs to be connected to the positive pole with a resistance of about 1k in series, otherwise there will be a current limiting resistor on the internal main board that will generate heat.The red motor is connected to the positive pole, the black is connected to the negative pole, and the white string 1k resistor is connected to the positive pole of the power supply. It needs to switch the green line to the negative pole, not the positive pole switch, the picture is wrong.(It is recommended to disconnect the white running line first to stop the motor, then turn on the green, and turn on the white line positive running).
Brushless motor positive and negative input power supply can not be mistaken, need to stabilize the power supply, can not be used to swing unregulated DC power supply.
The following is the actual test voltage and current and speed, for reference only.
Voltage 9v current 230ma speed 1200 rpm.
Voltage 12v current 160ma speed 1800 rpm.
Voltage 18v current 280ma speed 2700 rpm.
Voltage 24v current 340ma speed 3500 rpm.
The motor weighs 200 grams.
