Product Overview | Schneider EALU Series SH140/30270 High Performance Servo Motor
Core Positioning:
Schneider Electric”s EALU series servo motor, model SB145-30-08-05-24-P-01-64-EAKN, 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. SB145-30-08-05-24-P-01-64-EAKN 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 high-pole count of a stepper motor allows it to produce high torque and operate smoothly at low speeds. They can respond quickly and accurately position without an encoder, and easily produce holding torque. However, due to the high coil inductance, pole count, and L/R constant, torque drops in the high-speed region. The low pole count and low coil inductance of a servo motor do not produce high starting torque, but they can maintain torque better across the entire speed range.Closed-loop feedbackBy definition, a servo motor must operate in a closed-loop control system, while a stepper motor typically operates in an open-loop control system. Servo motors use feedback to control the position, speed, or torque of the motor. Stepper motors are commanded to move to a specific position without feedback and may lose synchronization if overloaded.
