this motor excels in scenarios demanding dynamic response, precise positioning, and long-term stability.
Model Analysis | Decoding the SH140/30270 Configuration
1. SH31003S0001281 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).
Frequency conversion motors, on the other hand, useinverterto control the supply frequency and voltage of the motor, thus achieving precise regulation of the motor”s speed. The inverter will convert the fixed frequencypower supplyof the power grid into an adjustable frequency and voltage output, to achieve control of the motor”s operating frequency and speed.2. Structural differencesOrdinary motors are generally composed of stators, rotors, and shells, etc. The stator is wound with coils, and the rotor is the part that rotates to drive the motor. The structure of ordinary motors is relatively simple and is suitable for conventional working occasions.Compared to this, frequency conversion motors, in addition to containing the structure of ordinary motors, also add a parameter adjustable inverter. The inverter is usually composed of a rectifier, inverter, andcontroller, which is used to control the changes in the motor”s supply frequency and voltage. This makes the frequency conversion motor have higher control performance and adaptability, and can adapt to different operating environments and requirements.
