This is the popular DC Geared Motor featuring an additional magnetic quadrature type rotary encoder. The quadrature encoders provide two pulses which are out of phase, for sensing the direction of the shaft rotation.

Hence, this SPG30E-20K DC Geared Motor with Encoder features both advantages of position sensing as well as direction sensing of the rotating shaft. This application flexibility of the encoders will allow you to control the speed of the base motor very precisely.

The SPG30E-20K is a compact brushed DC motor. The SPG30E-20K DC Geared Motor with Encoder is a low-cost solution for projects such as the medium-size Robot, Omni Drive Robot etc.

This SPG30E-20K DC Geared Motor with Encoder equips 20:1 gearbox for giving the torque of 1.2 kg-cm. The output shaft of the motor is D-shaped which facilitates the better coupling. The shaft has the length os 15.5 mm with the diameter of 6mm.

This is very useful especially when we are building a pulling system or conveyor system. Two Hall effect sensors are placed 90° apart to sense and produce two output A and B which is 90 degree out of phase and allowing the direction of rotation to be determined.

The motor is rated at 12V which will produce 185 RPM with the torque as high as 1.2 kg-cm.

Mounting Instructions

For mounting, the depth of the thread of the motor is 3.2 mm. So, you need to use 3.2 mm length of M3 size screw (not included with the thickness of the bracket). The longer screw will damage the gearbox. You may need to consider the thickness of the bracket or other mechanisms that you need to attach to the motor for choosing the right length of the screw.

We are supplying 4 more types of such DC geared motors with Encoders,

SPG30E-270K : 12RPM, 12kg-cm

SPG30E-200K : 17RPM, 8kg-cm

SPG30E-60K : 75RPM, 2.6kg-cm

SPG30E-30K : 150RPM, 1.3kg-cm

Note: These SPG30E DC Geared motors are imported from Cytron Technologies who are the original manufacturers of these DC motors with Encoders. When you will receive the motor you will find that there is a label(which is the sign of genuine product) on the motor mentioning different Motor Ratings irrespective of the listing on robomart.com site. The reason behind that is as you know when we import products we first test them before supplying to the customers, in the testing of this motor we found a slight variation in the performance of the motor and so the ratings as supplied by Cytron Technologies on that label. Hence there are some ratings that are different but yet these are the genuine DC Geared Motors with Encoder from Cytron Technologies.
