Product catalog summary
Overview: The document provides detailed specifications and performance data for various models of ETEL's Ironcore Linear Motors, specifically the LMA11 and LMA22 series. Each model is characterized by its winding codes, peak force, continuous force, stall force, and other electrical and mechanical parameters.
Specifications: Each motor model is defined by several key specifications including:
  • Peak Force (Fp): The maximum force the motor can exert.
  • Continuous Force (Fc): The force the motor can maintain continuously.
  • Stall Force (Fs): The force at which the motor stalls.
  • Force Constant (Kt): The force per unit current.
  • Back EMF Constant (Ku): The voltage generated per unit speed.
  • Electrical Resistance (R20): Measured at 20°C.
  • Electrical Inductance (L1): The inductance of the motor.
  • Nominal Input Voltage (Udc): The standard operating voltage.
Performance: The performance of each motor is evaluated under free air convection conditions, with parameters such as peak current, continuous current, stall current, and maximum continuous power dissipation being specified. The document also includes graphs showing the relationship between force and speed for different winding codes and input voltages.
Safety and Usage: The document cautions against using the motors beyond their specified speed and force limits to avoid hazardous voltages and potential injuries. It emphasizes the responsibility of the customer to implement safety measures to ensure the motors operate within safe parameters.
Graphical Data: The document includes graphs that illustrate the force versus speed characteristics for different winding codes and input voltages, providing a visual representation of the motor's performance capabilities.
Additional Notes: The document notes that all specifications are subject to change without notice and that the ambient temperature for the specifications is 20°C, with a maximum coil temperature of 130°C.
