Product Overview | Schneider EALU Series SH140/30270 High Performance Servo Motor
Core Positioning:
Schneider Electric”s EALU series servo motor, model SM100/30/080/P0/44/S1/B0, 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. SM100/30/080/P0/44/S1/B0 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).
Different control precisionThe step angle of a two-phase hybrid stepper motor is generally 3.6 degrees and 1.8 degrees, while the step angle of a five phase hybrid stepper motor is generally 0.72 degrees and 0.36 degrees. There are also some high-performance stepper motors with smaller step angles. A stepper motor produced by Sitong Company for slow wire cutting machine tools, with a step angle of 0.09 degrees; The step angle of the three-phase hybrid stepper motor produced by BERGER LAHR in Germany can be set to 1.8 degrees, 0.9 degrees, 0.72 degrees, 0.36 degrees, 0.18 degrees, 0.09 degrees, 0.072 degrees, and 0.036 degrees through a toggle switch, compatible with the step angles of two-phase and five phase hybrid stepper motors.The control accuracy of the AC servo motor is ensured by the rotary encoder at the rear end of the motor shaft. Taking Panasonic”s fully digital AC servo motor as an example, for a motor with a standard 2500 line encoder, due to the use of quadruple frequency technology inside the driver, its pulse equivalent is 360 degrees/10000=0.036 degrees. For a motor with a 17 bit encoder, for every 217=131072 pulses received by the driver, the motor rotates once, resulting in a pulse equivalent of 360 degrees/131072=9.89 seconds. It is 1/655 of the pulse equivalent of a stepper motor with a step angle of 1.8 degrees.
