Model Analysis | Decoding the SH140/30270 Configuration
1. SB105/20/08/05/19/S/01/64/DAFL 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:1. Different control accuracies: The control accuracy of AC servo motors is determined by the rotary encoder at the rear end of the motor shaft; The precision of the stepper motor is fixed or set through a toggle switch.2. Different low-frequency characteristics: Stepper motors are prone to low-frequency vibration at low speeds; The AC servo motor operates very smoothly without low-frequency vibration and has resonance suppression function.The above is the basic knowledge of stepper motors, hoping to be helpful to users.
Technical Features | Precision Control Meets High Efficiency
