Sanyo Pancake Stepper Motor with Encoder: Bipolar, 200 Steps/Rev, 42×24.5mm, 3.5V, 1 A/Phase, 4000 CPR

This NEMA 17-size pancake bipolar stepping motor from Sanyo features an integrated high-resolution (1000 P/R) quadrature encoder that allows for 4000 counts per revolution of the output shaft when counting both edges of both channels. The stepper motor itself has a 1.8° step angle (200 steps/revolution) and each phase draws 1 A at 3.5 V, allowing for a holding torque of 0.85 kg-cm (12 oz-in).

The stepper motor itself has a 1.8° step angle (200 steps/revolution) and each phase draws 1 A at 3.5 V, allowing for a holding torque of 0.85 kg-cm (12 oz-in). The motor has four color-coded wires terminated with bare leads: red and yellow connect to one coil; orange and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver or one of our Tic Stepper Motor Controllers. In particular, the Tics make control easy because they support six different interfaces (USB, TTL serial, I²C, RC, analog voltages, and quadrature encoder) and are configurable over USB with our free configuration utility.Our 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft, and our NEMA 17 aluminum bracket offers a variety of options for mounting this stepper motor in your project.This stepper motor is also available without an encoder.More specifications are available in the SS242x stepper motor datasheet (385k pdf) and the product-specific SS2421-50XE100 datasheet (568k pdf).DimensionsDimensions (in mm) of the SS2421-50XE100 42×24.5mm Sanyo pancake stepper motor with encoder.We also carry a taller version of this stepper motor with identical dimensions except for the height.

Side view of the SS2422-50XE100 42×31.5mm Sanyo pancake stepper motor. Quadrature encoderThe integrated quadrature encoder operates from 5 V and has a resolution of 1000 P/R, which allows for 4000 counts per revolution (CPR) of the output shaft when counting both edges (i.e. rising and falling) of both channels (i.e. A and B). In addition to the A and B channel outputs, the encoder has a home channel, Z, that pulses once per revolution and can be used for absolute positioning. The encoder also has outputs for the inverse of A, B, and Z. A 15 cm (6″) encoder cable is included.

Here are a few applications where stepper motors are often found:Sanyo stepper motors; from left to right: 14mm single shaft, 42×18.6mm, 50×11mm, 14mm double shaftNote: Sanyo Denki calls this product the “SANMOTION F2 STEPPING SYSTEMS TYPE SS2421-50XE100”.
