Product Overview | Schneider EALU Series SH140/30270 High Performance Servo Motor

Core Positioning:
Schneider Electric”s EALU series servo motor, model SM140/30/370/P1/45/S1/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. SM140/30/370/P1/45/S1/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).

2, The frequency characteristics of the stepping motor and the servo motor are different.The output torque of a stepper motor decreases as the speed increases, and it drops sharply at higher speeds, so its maximum operating speed is generally between 0 and 900RPM. An AC servo motor, on the other hand, provides constant torque output, meaning it can output the rated torque within its rated speed range (usually between 1000 and 3000RPM).3, The overload capacity of the stepper motor and the servo motor is different.4, The stepping motor and servo motor have different running performances. The control of stepping motor is open-loop control, and it is easy to appear stepping loss or stall when the starting frequency is too high or the load is too large, and it is easy to appear overshoot when the speed is too high at stop, so in order to ensure its control accuracy, the acceleration and deceleration problems should be handled well.
