Core Operations
- High-Force Delivery: Its primary function is providing 19.1 N-m of continuous torque, with an instantaneous peak capability of 57.29 N-m. This is essential for moving heavy mechanical components, such as large CNC spindles or industrial robotic joints.
- Stable Torque at 1500 RPM: Unlike smaller models rated at 3000 RPM, this motor is optimized for a rated speed of 1500 RPM. This allows it to deliver higher torque directly to the load, often reducing the need for high-ratio gearboxes.
- Inertia Buffering: The Medium Inertia rotor acts as a mechanical stabilizer. It functions as a buffer to prevent vibrations and "jitter" when the motor is attached to large mechanical systems (high load-to-motor inertia ratios), such as heavy gantry arms or large-format milling machines.
- Closed-Loop Precision: Utilizing a 22-bit high-resolution encoder, the motor provides real-time feedback to the drive to ensure the shaft reaches its exact commanded position and corrects any errors instantaneously. [1, 3, 4]
Industrial Applications
This 3kW motor is typically used for heavy-duty industrial tasks: [
