This geared motor is a powerful 12V DC motor with an 18.75:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 Zähls per revolution of the motor shaft, equivalent to 1200 Zähls per revolution of the gearbox output shaft. These units have a 16 mm long, 6 mm diameter D-shaped output shaft. This geared motor is also available without encoder.

Main specifications at 12 V: 500 rpm and 300 mA freewheel, 84 oz-in (6 kg-cm) and 5 A stall.

Note:

The overtightening or overloading of gearmotors can greatly shorten their service life and even lead to immediate damage. Standstills can also lead to rapid thermal damage (usually within seconds) to the motor windings and bearings; a general recommendation for operating a Brushed DC motor is 25% or less of the standstill current.

These motors are intended for use at 12 V, although these types of motors can generally operate at voltages above and below the rated voltage (they can rotate at voltages up to 1 V). Lower voltages may not be practicable, and higher voltages may adversely affect motor life.

Use encoderbr />
>A dual-channel Hall effect encoder is used to detect the rotation of a magnetic plate on a rear protrusion of the motor shaft. The quadrature encoder provides a resolution of 64 Zäs per revolution of the motor shaft when Zählen both edges of both channels. To calculate the number of revolutions per revolution of the gearbox output, multiply the ratio by 64. The motor/encoder has six color-coded, 8″ (20 cm) wires terminated with a 1×6 socket strip with a pitch of 0.1″, as shown in the main product image. This pin header works with standard 0.1″ pin headers and our optional jumper and pre-crimped cables. If this pinheader is not suitable for your application, you can pull the crimped wires out of the pinheader or cut the pinheader. The following table describes the wire functions:

Red: Motor power (connects to one motor terminal)
Black: Motor power (connects to the other motor terminal)
Green: Encoder GND
Blue: Encoder Vcc (3.5 - 20 V)
Yellow: Encoder A output
White: Encoder B output

The Hall sensor requires an input voltage, Vcc, between 3.5 and 20 V and draws a maximum of 10 mA. The outputs A and B are square waves from 0 V to Vcc, which are about 90° out of phase. The frequency of the waves gives you the speed of the motor, and the order of the waves gives you the direction.
