Model Analysis | Decoding the SH140/30270 Configuration
1. SH31004P12F2100 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).
Stepper motor control method; difference between stepper motor and servo motor.Stepper motorControl methodStepper motor is an electric motor thattranslateselectricsignalsintomechanicalrotation, and its output rotation angle changes according to the change of the electric pulse control signal. There are several common control methods for stepper motors, including full-step control, half-step control, and micro-step control.Full-step control: Full-step control is themost basic control method forsteppermotors. It controls therotation of the motor by controlling theHalf-step control: Half-step control can improve the resolution of a stepper motor. In full-step control, the motor can only rotate a fixed step angle, whereas in half-step control, the motor can rotate at half the step angle. Specifically, when the current flows clockwise through the first coil, the motor will rotate half a step angle forward, and when the current flows counterclockwise through the first coil, the motor will rotate the same angle backward. Then, the current will flow clockwise through the first coil and the second coil, causing the motor to rotate forward again by half a step angle. By alternately controlling the direction of the current, more precise control can be achieved, improving the accuracy and resolution of the stepper motor.
