Product Overview | Schneider EALU Series SH140/30270 High Performance Servo Motor
Core Positioning:
Schneider Electric”s EALU series servo motor, model SM-070/60/020/P1/45/M1/B1, 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. SM-070/60/020/P1/45/M1/B1 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).
Servo motorServomotors (as shown above) use a radially magnetized rotor instead of teeth (as shown below), which is the main reason for the significantly reduced pole count. The reduced pole count also requires the use of encoder feedback to minimize error.Servo motor designs typically use a 2- to 8-pole rotor and a 3-phase stator (U, V, W). Its rotor is segmented with radially magnetized permanent magnets, unlike the axial magnetization of a stepper motor.On the right is shown an example of a 4-pole rotor and a 6-pole stator design.As you can see, the number of poles available from the servo motor is significantly less due to the lack of teeth.
Technical Features | Precision Control Meets High Efficiency
1. Core Performance Parameters
Power & Torque:
- SM-070/60/020/P1/45/M1/B1 Rated power: Estimated 1.5kW–2.2kW (refer to selection manual).
