The PP520 disc magnet stepper motor is a high-speed, low-inertia motor designed for precise positioning in compact applications. It has a 52 mm diameter and a 3.6-degree step angle, with 100 steps per revolution. The PP520 258 004 01 variant has a phase resistance of 0.7 ohms, a phase inductance of 1.3 mH, and a nominal phase current of 2.30 A for two-phase drive, delivering 120 mNm holding torque at nominal current. Rotor inertia is 12.000 × 10⁻⁷ kgm², and the motor uses ball bearings. It operates within -20 to 50 °C ambient temperature and withstands a maximum coil temperature of 130 °C. The dielectric withstanding voltage is 500 VRMS for 5 seconds. Radial and axial shaft loads are rated at 20 N and 30 N respectively. Weight is 180 g.
