Beschreibung
The DS25mm Series is a frameless motor family built around a 25 mm stator outer diameter and a compact low-mass rotor/stator set. The listed version, 25ZWC10X-1, uses a 12-slot, 7-pole-pair design with star winding, 120° commutation, and no integrated feedback method. It is specified for 24 VDC operation, insulation class F, and S2 duty.
Key performance data supports high-speed compact drive integration. No-load speed reaches 26000 RPM, with a nominal speed of 22650 RPM. Nominal output is 70 W with 0.032 N·m nominal torque, while peak torque reaches 0.105 N·m at 13 A peak current. The motor has 0.42 Ω phase resistance, 0.123 mH phase inductance, a torque constant of 0.009 Nm/A, and a back-EMF constant of 0.65 Vrms/Krpm. Low moving mass is supported by a 3.2 g rotor weight and 1.47 g·cm² rotor inertia.
- Frameless 25 mm platform for compact embedded drive assemblies
- High-speed capability up to 26000 RPM with 22650 RPM nominal speed
- 70 W nominal power from a lightweight stator/rotor set
- Peak torque of 0.105 N·m for short-duty load demand
- Suitable for applications that require an external feedback solution or sensorless operation, as no feedback device is integrated
Typical use cases are compact high-speed systems where the motor is integrated directly into the machine structure and low rotor inertia is beneficial. Electrical insulation data includes 600VAC/3mA/1s dielectric strength and 50 MΩ insulation resistance at 500 VDC. The stator weight is 22 g, and the rotor inner bore is 11.6+0.046 mm.
