It offers a holding torque of 1.9 kg-cm (26 oz-in), and each phase draws 1 A at 5.4 V. This stepper motor’s flat profile (25.6 mm including the shaft) allows it to be used in places where more traditional stepper motors would be too bulky. ## Pricing - **Price:** $159.95 (inc GST) — $145.41 AUD, exc GST - **Quantity discounts:** 5+ $139.59 (exc GST) · 10+ $135.23 (exc GST) ## Availability & dispatch - Out of stock — the product page offers email notification when it returns. ## Description | [![](https://core-electronics.com.au/attachments/localcontent/0J4301_21501cc580f.jpg)](https://core-electronics.com.au/attachments/localcontent/0J4301_166092c56e0.jpg) | |---| | Bipolar stepper motor wires are terminated with bare leads. | | ![](https://core-electronics.com.au/attachments/localcontent/0J4307_1157645e221.jpg) | |---| | Sanyo bipolar stepper motor wiring diagram. | This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 5.4 V, allowing for a holding torque of 1.9 kg-cm (26 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-42-31-5mm-5-4v-1-a-phase-4000-cpr.html). **Specifications** - Size: 42 mm square × 18.6 mm, not including the shaft (NEMA 17) - Weight: 140 g (4.9 oz) - Shaft diameter: 5 mm - Steps per revolution: 200 - Current rating: 1 A per coil - Voltage rating: 5.4 V - Resistance: 5.4 O per coil - Holding torque: 1.9 kg-cm (26 oz-in) - Inductance: 2.9 mH per coil - Lead length: 30 cm (12") - Output shaft supported by two ball bearings More specifications are available in the datasheet (385k pdf). **Dimensions** The following diagram shows the stepper motor dimensions in mm. The dimension labeled “L” is 18.6 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://core-electronics.com.au/attachments/localcontent/0J4298_43559c9cc65.jpg) | |---| Pololu also carry a [thinner version of this stepper motor](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-42-11-6mm-3-5v-1-a-phase.html) where “L” in the above diagram is 11.6 mm and all other dimensions are the same. | [![](https://core-electronics.com.au/attachments/localcontent/0J4303_266031fee06.jpg)](https://core-electronics.com.au/attachments/localcontent/0J4303_20348f2b237.jpg) | |---| | Bottom view of the 42×18.6mm 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://core-electronics.com.au/attachments/localcontent/0J4306_4154284e0c4.jpg) | |---| | 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 SS2422-5041 (or SS2422-5041P)”. **People often buy this product together with:** | [![Pololu Universal Aluminum Mounting Hub for 5mm Shaft, #4-40 Holes (2-Pack)](https://core-electronics.com.au/attachments/localcontent/0J2468_33052118e3.jpg)](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) | |---|---| | [![Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 50×11mm, 4.5V, 1 A/Phase](https://core-electronics.com.au/attachments/localcontent/0J4304_3320b3b24c.jpg)](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-50-11mm-4-5v-1-a-phase.html) | [Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 50×11mm, 4.5V, 1 A/Phase](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-50-11mm-4-5v-1-a-phase.html) | |---|---| | [![Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 42×11.6mm, 3.5V, 1 A/Phase](https://core-electronics.com.au/attachments/localcontent/0J4486_396650fb86.jpg)](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-42-11-6mm-3-5v-1-a-phase.html) | [Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 42×11.6mm, 3.5V, 1 A/Phase](https://core-electronics.com.au/sanyo-pancake-stepper-motor-bipolar-200-steps-rev-42-11-6mm-3-5v-1-a-phase.html) | |---|---| **Dimensions** | Size: | 42 mm square × 18.6 mm (NEMA 17)[1](https://core-electronics.com.au/#note1) | |---|---| | NEMA size: | 17 | | Weight: | 140 g | | Shaft diameter: | 5 mm | **General specifications** | Current rating: | 1000 mA[2](https://core-electronics.com.au/#note2) | |---|---| | Voltage rating: | 5.4 V | | Holding torque: | 26.33 oz·in | | Steps per revolution: | 200 | | Resistance: | 5.4 Ohm[2](https://core-electronics.com.au/#note2) | | Inductance per phase: | 2.9 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_42x18.6mm_5.4v_1_a_phase__pololu_2296__00.jpg)
