Description
19**NH…M… Series: High-Performance 19mm Coreless Brushless DC Servo Motors
The 19**NH…M… family delivers exceptional dynamics in compact form with their 19mm diameter coreless, brushless construction. These micro DC servo motors provide high-speed operation, superior torque-to-weight ratio, and precision control—ideal for critical applications where space and performance are paramount.
- No-load speed: Up to 48,200 rpm across voltage options (24V, 36V, 48V)
- Torque: Nominal torque up to 21 mNm and stall torque up to 358.8 mNm
- Brushless, coreless design: Provides low inertia, rapid acceleration, and minimal cogging for smooth motion control
- Encoder options: Integrated encoders with up to 3 channels; selectable counts per turn (16 to 1024 cpt) and TTL signal output
- Electrical features: Terminal resistance from 0.36Ω to 1.41Ω; Back-EMF constants from 0.496 to 0.992 mV/rpm; operational from -20°C to +85°C
- Customization: Options for shaft length, special coils, and lead wire length adaptation
Applications: Suited for medical equipment (e.g., compact pumps, laboratory automation), high-precision robotics and actuator systems, and sensitive measuring or instrumentation devices.
Benefits: High-speed performance in a micro form factor; reliable, maintenance-free operation due to brushless technology; easy integration with advanced encoder feedback for position/speed monitoring. An excellent choice for demanding automation and mechatronic designs requiring accuracy, responsiveness, and miniature footprint.
