Description

SM2019 12V Permanent Magnet Stepper Motor

The SM2019 is a 12V permanent magnet stepper motor designed for applications requiring controlled step-by-step rotation. It features a 2-phase winding configuration and operates with a rated drive voltage of 12V ±0.2V. The motor has an 18° step angle and uses a 2-2 bipolar excitation method.

Key Product Features

The SM2019 supports clockwise and counterclockwise rotation when viewed from the output-shaft side. Its winding resistance is 20 Ω per phase with a tolerance of ±7% at 20°C. The reference winding inductance is 11 mH per phase at 20°C.

The motor provides a holding torque of at least 50 g·cm, pull-out torque of at least 60 g·cm at 500 pps, and pull-in torque of at least 40 g·cm at 500 pps.

Technical Specifications

The motor weighs approximately 26.6 g. Its operating temperature range is 0 to +55°C, and its storage temperature range is −20 to +65°C. Both ranges require conditions without condensation. The specified operating humidity range is 5–90% RH.

Applications

The SM2019 12V stepper motor can be evaluated for compact motion-control equipment and control systems that require repeatable step positioning.

Actual suitability depends on the load, driver, operating speed, mounting arrangement and working environment.
