Model Analysis | Decoding the SH140/30270 Configuration

1. SM140/30/120/P0/44/R1/B0/01 Series Designation: SH140

Represents the medium-to-large power range, with an estimated power output of 0.75kW–3kW.

2. Core Parameter Code: 30270

This code encompasses critical specifications such as speed, torque, and encoder resolution.
For example, it may indicate:

Rated speed: 3000 rpm
Rated torque: 2.7 Nm
(Actual values depend on the full parameter set.)

3. Configuration Fields: 0/1/00/00/00/00/00

These digits define additional options, including but not limited to:

Voltage level
Protection rating (e.g., IP65)
Communication protocol (e.g., EtherCAT, CANopen)
Functional add-ons (e.g., brakes, oil seals).

The difference between stepper motor and servo motor:The feedback control methods are different: stepper motors are controlled based on input pulse signals, without feedback control, so they cannot perceive and correct position errors; The servo motor obtains actual position information through feedback devices (such as encoders), compares it with the set position, and adjusts the motor speed and direction through control signals to make the actual position consistent with the set position.2. Different application scenarios: Stepper motors are suitable for situations that require precise positioning and low speed, such as printers, plotters, etc; Servo motors are more suitable for applications that require high-precision and high-speed control, such as machine tool processing, robots, CNC equipment, etc.Different control methods: The control of stepper motors is relatively simple, only requiring the provision of pulse signals; And servo motors require PID control, which requires real-time adjustment of motor speed and direction through control algorithms.A stepper motor is a type of motor that rotates according to a certain number of steps, characterized by high precision, high reliability, and relatively low cost. It is widely used in fields such as machine tools, 3D printing, robots, and automation equipment.
