12V/0.8Kg-cm/46RPM 50:1 DC Gear Motor w/ Encoder

ID: 3256E_0

This DC motor has an encoder, a 50:1 gearbox, a rated speed of 46 RPM and rated torque of 0.82 Kg·cm.

Discontinued

The 3256E is a 12 volt gear motor, generating 0.82 Kg-cm of torque at 46 RPM. It is very efficient for its size, so less power is lost in the form of heat.

This motor comes equipped with an E4P US Digital Encoder, which keeps track of the motor's rotation, allowing you to control your motor precisely.

This family of motors (3254, 3255, 3256, 3257) have the same gearbox type and mounting metrics as the (3258, 3259, 3260) family of motors.

Connection

This motor can be controlled by a DC motor controller. You can find a list of suitable controllers on the Connection & Compatibility tab.

Comes packaged with

DC Motor Controllers

DC motors can be simply connected to a power supply according to their rated voltage in order to make them run, but if you want to have control over direction, velocity, and acceleration in real-time, you'll need to use a motor controller. In order to connect this motor to a controller, you'll need to solder wires to the contacts on the back of the motor and connect those wires to the motor terminal on the controller. Don't worry about wiring the motor backwards; doing so will only reverse the direction of rotation.

Encoder Interfaces

If you decide to use a motor controller without an encoder input, you'll need an interface to read data coming from the quadrature encoder.

Pulleys and Sprockets

If you're using this motor to drive a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the motor. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance.
