Product Description

The 25W Brush DC Gear Motor offers high performance and adaptability, perfect for a range of industrial and hobbyist applications. With a frame size of 70mm x 70mm, this motor is designed to fit into confined spaces without compromising on power. It operates on a wide voltage range of 12-90V, providing flexibility for various power sources and control systems.

In no-load conditions, the motor runs at a speed of 3100-3300 RPM, drawing a current between 0.3-1.0A. When under load, the speed decreases slightly to 2700-3000 RPM, with a corresponding current draw of 0.6-3.5A. This motor delivers a torque of 80-88mN.m, ensuring it can handle demanding tasks with ease.

The 25W Brush DC Gear Motor is ideal for applications that require precise speed and torque control. It is suitable for use in robotics, automated systems, small machinery, and other projects where reliability and performance are essential. The motor’s broad voltage and current ranges enhance its compatibility with diverse electronic controllers and power setups.

Motor voltage, power and speed will be customized according to his requestment under the allowed circumstance of adoptable dimension

We use W after D in the model to express the external brush motor. such as Z20W06-12GN.lf no W, it means the standard internal brush motor For external brush motor, you can replace the brush directly. For internal ones, we need to disassembly the motor first.

Gearheads are sold separately. Decimal gearheads are not available.

Enter the gear ratio in the box (□) within the model name.

The colored background (□) indicates the same rotating direction of the motor while the rotating direction of others are opposite.

The speed is calculated by dividing the motor's synchronous ped by the gearatio. The actual speed is 2%~20% less than the displayed value, depending on the size of the load.

To reduce the speed beyond the gear ratio in the table, attach a decimal gearhead (gear ratio:10) between the gearhead and motor. In that case, the permissible torque is 5Nm.
