Factory Micro Pm Stepper Gear Motor for Valve

Product Description

Features of Derry's Stepper motors

- 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 (Power-Off Holding):Maintains position when unpowered via permanent magnet attraction.
- High Torque at Low Speed:Strong torque at low speeds; direct drive without gearbox.
- Fast Response & Easy Control:Quick start/stop/reverse; speed via pulse frequency; open-loop accurate positioning.
- Low Power & Low Noise:Low control power, quiet operation (~35dB).
- 2/4-Phase, Compact:Small size, light weight; mostly bipolar drive.
- Limitations:Moderate high-speed performance; lower resolution than hybrid steppers.

Faqs

1. What is a PM stepper motor?
A brushless DC motor that rotates in fixed steps using a permanent magnet rotor, ideal for simple positioning.
2. What is the typical step angle?
Usually 7.5° or 15°, providing basic positioning accuracy.
3. Does it hold position when powered off?
Yes, it has detent torque from the permanent magnet.
4. How to reverse rotation?
Reverse the driving phase sequence or change the DIR signal on the driver.
5. Why does it miss steps?
Overload, excessive speed/acceleration, insufficient power, or mechanical issues.
6. Is it good for high speed?
No, it performs best at low to medium speeds.
7. Does it need a sensor?
Normally not; it works with open-loop control.
8. Main applications?
Printers, cameras, HVAC valves, medical devices, automotive actuators, and small consumer electronics.
9. Common voltage?
5V, 12V, 24V are widely used.
10. Advantages?
Low cost, simple control, low noise, and maintenance-free.
