NIMC2400-C10W Series Visualization Controller

The choice depends on your specific application. Stepper motor systems are suitable for applications with medium-to-low torque (generally below 20 Nm), low speed (below 2000 RPM), low cost, and are virtually maintenance‑free. Servo motor systems cover a wide torque range (low to high), offer higher speeds (up to 5000 RPM), support multiple control modes (position/speed/torque), provide high precision and smooth operation, and have strong overload capability (3‑10 times short‑term overload), but at a higher cost. In short: if your budget is limited, the load is stable, and speed is below 1000 RPM, a stepper motor is a good choice; if you need high precision, high speed, variable loads, or disturbance rejection for dynamic control, choose a servo motor.

Before selection, determine the following: load characteristics (e.g., horizontal or vertical); torque, inertia, speed, accuracy, acceleration/deceleration requirements; host controller interface and communication method; main control mode (position, torque, or speed); power supply type (DC or AC) and voltage range.

2‑phase motors are less expensive but exhibit more vibration at low speeds and have a steeper torque drop at high speeds. 5‑phase motors have lower vibration and better high‑speed performance – they can run 30‑50% faster than 2‑phase motors, and can replace servo motors in some applications. For general cost‑sensitive uses, choose 2‑phase; if vibration and high‑speed performance are critical, choose 5‑phase.

Low‑inertia motors have very low rotor inertia, offering faster acceleration and better dynamic response. High‑inertia motors provide higher torque accuracy, lower speed fluctuation, and smoother operation – they are suitable for applications that prioritise running stability.

Integrated stepper/servo motors combine the motor, driver, and encoder in one compact unit. They offer a smaller footprint, simpler wiring, reduced installation space, and fewer potential failure points. They also simplify commissioning and maintenance, making them ideal for automated equipment where space and reliability are critical.
