Stepper Servo System


Introduction

Stepper servo sytem is a control motor solution featuring high speed, high torque, high precision, low vibration, low heating and no loss of step, which is formed based on the common open loop stepper motor in combination with position feedback and servo algorithm.

Stepper servo system motor is equipped with a optical encoder on the rear shaft of the open-loop motor to form position feedback.

Stepper servo system drive processes the encoder position feedback to achieve more precise current and position control.

Rtelligent’s stepper servo system combines the advantages of both stepper motors and servo motors. It operates in a closed-loop fashion, offering the precision of servo motors while retaining the simplicity and cost-effectiveness of stepper motors.

These systems employ feedback devices like encoders to ensure accurate positioning and eliminate the risk of step losses. Stepper servo systems are highly suitable for applications demanding reliable, high-precision control, such as 3D printing and CNC machinery.

They offer engineers the flexibility to achieve intricate tasks with ease, bridging the gap between traditional stepper and servo motor technologies.

Features

Stepper Servo System

No Loss Of Steps

The position of the stepper servo motor is fedback by the optical encoder and compared with the drive command.The current is adjusted according to the position error to prevent losing step.

Stepper Servo System

Fast Response

The stepper servo motor rotor is synchronized with the given pulse, enabling fast positioning without rigidity adjustment without too long current settling time.

Stepper Servo System

High Torque

The stepper servo system has better torque-frequency characteristics, and the current decay speed is slow, which can improve the output torque of the motor at high speed.

Stepper Servo System

Low Heating

The stepper servo system dynamically adjusts the current according to the load condition, which has a higher current utilization rate than the open loop system and reduces the heating of the motor.
