Product Overview | Schneider EALU Series SH140/30270 High Performance Servo Motor
Core Positioning:
Schneider Electric”s EALU series servo motor, model SH31403P12F2100, is a high-precision, high-reliability drive solution tailored for industrial automation. By integrating Schneider”s advanced motor control technology with the modular EALU design,
this motor excels in scenarios demanding dynamic response, precise positioning, and long-term stability.
Model Analysis | Decoding the SH140/30270 Configuration
1. SH31403P12F2100 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).
Increase the motor scaleHowever, when we are unable to increase the slot filling ratio by means of production technology, we may choose to scale up the size of the motor as a strategy. This not only provides a larger slot space to accommodate the enamel coil, but we also know from the torque formula of the motor that there is a square relationship between the rotor diameter and the torque. For example, if the rotor diameter is increased from 50 to 60, although the diameter only increases by 1.2 times, the torque will increase by 1.44 times. If we maintain the same torque, this means that we can reduce the current by 1.44 times, thereby reducing the copper loss. Therefore, scaling up the motor size can significantly contribute to efficiency improvement. However, this also means that it will increase the material cost and storage and transportation cost, which may not be the best choice in thecommodification process.
