Product Overview | Schneider EALU Series SH140/30270 High Performance Servo Motor
Core Positioning:
Schneider Electric”s EALU series servo motor, model SB105/40/04/05/19/S/R1/64/EOKN, 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. SB105/40/04/05/19/S/R1/64/EOKN 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).
The advantage of a differential motor is that it has a wide range of speed control, suitable for high torque low-speed applications, and it is also efficient. However, due to the large friction loss of the differential, it generates more heat during long-term operation, requiring cooling. The advantage of a variable frequency motor is that it has a high efficiency, can achieve speed control according to actual needs, and can reduce the starting current of the motor, extending the life of the motor. However, the cost of the variable frequency drive itself is high, and it also causes a large amount of electromagnetic interference to the motor. Differential motors are mainly used in automotive drive systems, industrial machinery, and ships. On the other hand, frequency conversion motors are mainly used in fans, pumps, compressors, and other equipment, especially in the fields of energy-saving renovation and intelligent control.
