MOONS' PG15 Gearbox Permanent Magnet Stepper Motor: High-Precision Control in a Compact Size

Stepper motors, as open-loop control motors that achieve fixed step angle operation through pulse signal frequency and pulse number, possess the characteristic of no cumulative error and are widely used in angular and linear displacement control application. The MOONS' PG15 gearbox permanent magnet stepper motor leverages the advantages of permanent magnet stepper motors—small size and high speed—and, with its gearbox design, achieves a small step angle within a compact size. This effectively improves the precision and smoothness of the motor in rotational angle and linear displacement control, demonstrating excellent product performance.

The MOONS' PG15 series gearbox motors are divided into rotary and linear types, with outstanding performance and advantages in the field of precision control:

This series of motors can achieve small step angles of 0.9° and 0.36°, with step angle accuracy controlled within ±0.126°. When paired with a 0.5mm pitch lead screw to convert rotary motion into linear displacement, the PG15 geared stepper motor (0.36°) completes one revolution with 1000 pulses, achieving a linear displacement of 0.5mm. A single pulse can precisely control a linear displacement of 0.5μm, with a positional accuracy of ±0.175μm, meeting micron-level control requirements.

While achieving high-precision displacement control, the PG15 geared permanent magnet stepper motor exhibits excellent smooth operation. Compared to the 20mm 8HY series hybrid stepper motor, this motor exhibits superior vibration performance in the low-speed operating range (< 1rps). Whether driven by a 5V constant voltage or a 0.5A constant current, it maintains low vibration, making it suitable for precision applications requiring high operational stability.

The PG15 gearbox permanent magnet stepper motor has a main body diameter of φ15mm, offering a size advantage compared to the 14mm hybrid stepper motor (19.8mm diagonal). In the commonly used industrial speed range of 200rpm to 600rpm, this motor's torque performance is competitive: under 0.3A constant current drive conditions, the PG15 with a 1:5 reduction ratio offers over 30% higher torque than the 14mm hybrid stepper motor; the 1:10 reduction ratio product can achieve double torque at 350rpm.

The PG15 gearbox permanent magnet stepper motor boasts excellent low-voltage adaptability, maintaining normal operation in 5V battery-powered applications. In contrast, similar hybrid stepper motors offer virtually no output capability under such low-voltage conditions, making it more suitable for portable, low-power devices with specific voltage limitations.

MOONS' PG15 gearbox permanent magnet stepper motor achieves a comprehensive advantage of high precision, smooth operation, high torque, and wide voltage adaptability through its compact design. It is an excellent choice for stepper motors in miniaturized and precision industrial control and equipment applications, providing a reliable power solution for various precision displacement control needs.
