Model Analysis | Decoding the SH140/30270 Configuration
1. SM-070/60/020/P4/55/S1/B0 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).
2、 Control methodFOC motor:FOC motor adopts vector control method, which achieves efficient and smooth operation of the motor by accurately controlling the magnitude, direction, and phase of the motor stator current.FOC control technology can be applied to both sensory FOC and non sensory FOC scenarios. Sensing FOC detects rotor position through sensors, while non sensing FOC estimates rotor position through algorithms.BLDC motor:The control method of BLDC motor is relatively simple, usually using square wave control or sine wave control.The most representative method in square wave control is the six step commutation method, which generates a rotating magnetic field by switching the direction of current in different states. Sine wave control generates a smooth rotating magnetic field by continuously changing the magnitude and direction of the current.
