35mm 12VDC 2phase Permanent Magnet Stepper Motor Gear Motor for Valve

Product Description

Stepper Motor Features

Simple & Cost-Effective: Permanent magnet rotor, claw-pole stator; low manufacturing cost, high cost-performance.
Large Step Angle: Typically 7.5°/15°, medium precision for coarse positioning.
Detent Torque: Maintains position when unpowered via permanent magnet attraction (Power-Off Holding).
High Torque at Low Speed: Strong torque at low speeds; direct drive without gearbox.
Fast Response: Quick start/stop/reverse; speed via pulse frequency; open-loop accurate positioning.
Low Power & Noise: Low control power, quiet operation (~35dB).

Frequently Asked Questions

What is a PM stepper motor?
A brushless DC motor that rotates in fixed steps using a permanent magnet rotor, ideal for simple and reliable positioning.
What is the typical step angle for these motors?
The typical step angles are 7.5° or 15°, which provide a balance of positioning accuracy and control simplicity.
Does the motor maintain its position when powered off?
Yes, PM stepper motors feature detent torque, which allows them to hold their position even when unpowered via permanent magnet attraction.
What are the main applications for these motors?
Common applications include printers, HVAC valves, medical devices, automotive actuators, cameras, and various small consumer electronics.
Can the rotation direction be reversed?
Yes, you can easily reverse the rotation by changing the driving phase sequence or the DIR signal on the motor driver.
What voltages are commonly used?
The most widely used voltages for these stepper motors are 5V, 12V, and 24V.
