Each phase draws 1 A at 3.5 V, allowing for a holding torque of 850 g-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 Pololu recommend using a [bipolar stepper motor driver](https://core-electronics.com.au/breakout-boards-and-modules/motor-drivers-controllers/stepper-motor-drivers.html) or one of Pololu's [Tic Stepper Motor Controllers](https://core-electronics.com.au/breakout-boards-and-modules/motor-drivers-controllers/stepper-motor-drivers.html). 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 Pololu's free configuration utility. Pololu's [5 mm universal mounting hub](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-5mm-shaft-4-40-holes-2-pack.html) can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft, and Pololu's [NEMA 17 aluminum bracket](https://core-electronics.com.au/pololu-stamped-aluminum-l-bracket-for-nema-17-stepper-motors.html) offers a variety of options for mounting this stepper motor in your project. This stepper motor is also available [with a high-resolution quadrature encoder](https://core-electronics.com.au/sanyo-pancake-stepper-motor-with-encoder-bipolar-200-steps-rev-42-24-5mm-3-5v-1-a-phase-4000-cpr.html). **Specifications** - Size: 42 mm square × 11.6 mm, not including the shaft (NEMA 17) - Weight: 70 g (2.5 oz) - Shaft diameter: 5 mm - Steps per revolution: 200 - Current rating: 1 A per coil - Voltage rating: 3.5 V - Resistance: 3.5 O per coil - Holding torque: 850 g-cm (12 oz-in) - Inductance: 1.2 mH per coil - Lead length: 30 cm (12") - Output shaft supported by two ball bearings More specifications can be found in the datasheet (385k pdf). **Dimensions** The following diagram shows the stepper motor dimensions in mm. The dimension labeled “L” is 11.6 mm. This stepper motor has a single output shaft with a length of 5 mm from the mounting face and a diameter of 5 mm. This shaft works with Pololu's [5 mm universal mounting hub](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-5mm-shaft-4-40-holes-2-pack.html). | ![](https://a.pololu-files.com/picture/0J4298.700.jpg?044319c8444d64c247adaebd3dfc42bf) | |---| Pololu also carry a [stronger, taller version of this stepper motor](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-42-18-6mm-5-4v-1-a-phase.html) where “L” in the above diagram is 18.6 mm and all other dimensions are the same. | [![](https://a.pololu-files.com/picture/0J4487.300.jpg?f31d1565d00f70762e5a976600ab129b)](https://a.pololu-files.com/picture/0J4487.1200.jpg?f31d1565d00f70762e5a976600ab129b) | |---| | Bottom view of the 42×11.6mm Sanyo pancake stepper motor. | **Stepper Motor Applications** Stepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is unwarranted. Here are a few applications where stepper motors are often found: - Printers - CNC machines - 3D printer/prototyping machines (e.g. RepRap) - Laser cutters - Pick and place machines - Linear actuators - Hard drives | ![](https://a.pololu-files.com/picture/0J4306.600.jpg?1b654e902c4b380ea21d7bbc77eb7937) | |---| | Sanyo stepper motors; from left to right: 14mm single shaft, 42×18.6mm, 50×11mm, 14mm double shaft | **Note:** Sanyo Denki calls this product the “SANMOTION F2 STEPPING SYSTEMS TYPE SS2421-5041 (or SS2421-5041P)”. **People often buy this product together with:** | [![Pololu Universal Aluminum Mounting Hub for 5mm Shaft, #4-40 Holes (2-Pack)](https://a.pololu-files.com/picture/0J2468.100.jpg?48f58383f75147660070803af59277ee)](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-5mm-shaft-4-40-holes-2-pack.html) | [Pololu Universal Aluminum Mounting Hub for 5mm Shaft, #4-40 Holes (2-Pack)](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-5mm-shaft-4-40-holes-2-pack.html) | |---|---| | [![Stepper Motor: Bipolar, 200 Steps/Rev, 20×30mm, 3.9V, 0.6 A/Phase](https://a.pololu-files.com/picture/0J2280.100.jpg?82c52fb5c8727b3b7d16a0a6fd16dab6)](https://core-electronics.com.au/stepper-motor-bipolar-200-steps-rev-20-30mm-3-9v-0-6-a-phase.html) | [Stepper Motor: Bipolar, 200 Steps/Rev, 20×30mm, 3.9V, 0.6 A/Phase](https://core-electronics.com.au/stepper-motor-bipolar-200-steps-rev-20-30mm-3-9v-0-6-a-phase.html) | |---|---| | [![Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 42×18.6mm, 5.4V, 1 A/Phase](https://a.pololu-files.com/picture/0J4302.100.jpg?c331e56c4c216ee04f9c1ffdd8fbaabf)](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-42-18-6mm-5-4v-1-a-phase.html) | [Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 42×18.6mm, 5.4V, 1 A/Phase](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-42-18-6mm-5-4v-1-a-phase.html) | |---|---| **Dimensions** | Size: | 42 mm square × 11.6 mm(NEMA 17)[1](https://core-electronics.com.au/#note1) | |---|---| | NEMA size: | 17 | | Weight: | 70 g | | Shaft diameter: | 5 mm | **General specifications** | Current rating: | 1000 mA[2](https://core-electronics.com.au/#note2) | |---|---| | Voltage rating: | 3.5 V | | Holding torque: | 11.8 oz·in | | Steps per revolution: | 200 | | Resistance: | 3.5 Ohm[2](https://core-electronics.com.au/#note2) | | Inductance per phase: | 1.2 mH | | Number of leads: | 4 | | Lead length: | 30 cm | | Encoders?: | N | **Notes:** 1Not including the shaft.2Per coil. **File downloads** - **Sanyo Sanmotion F2 42mm SS2421 and SS2422 stepping motor datasheet (385k pdf)** ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/s/a/sanyo_pancake_stepper_motor_bipolar_200_steps_rev_42x11.6mm_3.5v_1_a_phase__pololu_2298__00.jpg)
