775 Carbon Brush Motor DC 12-24V High Speed High Power Motor with Cooling Fan, Front Ball Bearing 9900-20000 RPM Shaft Dia 5mm

High-speed and high-power 775 DC motor, it is estimated that it is used in electric tools, front ball bearing, workmanshis very good, especially the carbon brush is simple and easy to replace, twist the black cover to easily replace the carbon brush, the whole shell plating Zinc is very bright, the speed is also moderate, the rated voltage is 18V, the speed is 12000 rpm for one minute, the actual test 12-24v is no problem, the temperature rise is not obvious, see the actual need to choose the voltage! This motor is estimated to be designed with a gearbox with a reduction gearbox. The shaft is a bit short and only 6.8mm long. This seto be a disadvantage, but the things are two-sided. This length is suitable for installing a pulley-driven unpowered shaft. You can install a taper to connect the copper sleeve, you can directly drill the chuck, just right for the electric spindle of the bench drill. As we all know, the longer the shaft, the lower the mechanical strength and the worse the concentricity. Motor diameter: 45 MM Motor length: 75 MM (excluding front axle and step) Output shaft: 5 MM Output shaft length: 6.8 MM. (from the panel) Weight: 380g The following are the no-load speed and current parameters of different voltages. Voltage: 12 V Current: 1.2A Speed: 9900 RPM Voltage: 18 V Current: 1.4A Speed: 14800 RPM Voltage: 24 V Current: 1.7A Speed: 20000 RPM This motor has a relatively large power, and the power supply requirements are relatively high.
