Product Overview | Schneider EALU Series SH140/30270 High Performance Servo Motor
Core Positioning:
Schneider Electric”s EALU series servo motor, model ISH140/20125/0/1/00/0/00/10/00, 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. ISH140/20125/0/1/00/0/00/10/00 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).
Servomotors need more space due to the requirements of absolute encoders. The lower pole count allows it to produce higher torque at higher speeds. Stepper motors can operate in an open loop without an encoder, making them more compact.Stop accuracyFor positioning applications, one of the key requirements that we must meet is the accuracy of the motor”s stop. Both stepper and servo motors can stop accurately.The stop accuracy of a stepping motor depends on the quality of the winding (electrical) and the tooth structure (mechanical), while the accuracy of a servo motor depends on the assembly accuracy, the encoder resolution andalgorithm.Remember that the air gap between the rotor and stator is very thin, and the only friction is from its ball bearings. Frictional torque or gravity load will cause a deviation in the actual stopped position, so there is a little error when you move from one position to another. The errors that occur when we plot one full rotation of the motor are shown in the figure below.
