TT geared motor - 3-6 V, 1:90, all-metal gearbox, dual shaft

Product Overview

• Gear motor with 3 mm shaft diameter and 6 V operating voltage
• 1:90 gear ratio for high torque at low speed
• All-metal gearbox for long-term use
• DC motor with simple two-wire control
• Compact design for mobile robots and model vehicles

Product Description

An all-metal gear motor withstands reverse polarity and impacts during operation significantly better than plastic gearboxes. This motor operates on 6 V DC and has a 1:90 gear ratio, making it suitable for tasks requiring high torque at low speed.

The motor's 3 mm shaft fits standard model wheel hubs or can be connected using small couplings. To control the motor directly, you only need two wires and a suitable power supply, as no switching regulator is required. To change the direction of rotation, reverse the connections.

The motor is suitable for autonomous mobile robots, where the gear ratio limits the travel speed to about 1 to 2 meters per minute while providing high traction. The gearbox also delivers reliable propulsion in remote-controlled model vehicles powered by a rechargeable or disposable battery. Window-cleaning or painting robots also benefit from its compact size and robust all-metal construction.

A 6 V DC power supply is required for operation. Power switches or relays used to control multiple motors must be rated for the motor's current draw. With standard microcontroller boards, the motor can be switched using transistors or motor driver modules.

Safety Notice

This motor is intended exclusively for building prototypes and for testing and development purposes. It is not suitable for installation in household electrical wiring. When operating with lithium batteries or in damp environments, ensure that the connections are adequately insulated. If you have questions about safe commissioning in higher-power systems, consult a qualified electrician.
