Product Description

The 40W Brush DC Gear Motor offers high performance and adaptability, perfect for a range of industrial and hobbyist applications. With a frame size of 80mm x 80mm, 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 3000-3200 RPM, drawing a current between 0.2-1.4A. When under load, the speed decreases slightly to 2850-3100 RPM, with a corresponding current draw of 0.6-3.5A. This motor delivers a torque of 77-84mN.m, ensuring it can handle demanding tasks with ease.

The 40W 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.

Gear Motor-Torque Table

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 speed by the gear ratio. The actual speed is 2%~20%lessthan 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 8Nm.
