A-B MPL-B220T-EJ74AA

  • Low Inertia: Enables rapid acceleration and deceleration for applications needing high responsiveness and precise positioning.
  • Permanent Magnet Design: Offers several advantages over DC brushed motors:
    • Higher efficiency and lower maintenance due to the absence of brushes.
    • Smoother operation and reduced torque ripple for improved control.
  • Hiperface Single-Turn Absolute Encoder (Likely): Likely integrates a high-resolution absolute encoder that provides the motor’s exact position information at any time. This eliminates the need for homing procedures during startup.
  • 24V DC Brake (Possible): May include a built-in DC brake that helps hold the motor shaft stationary when power is removed, improving safety and machine control.
  • Circular DIN Connector: Offers a quick-connect and easy-to-assemble power connection.
  • Keyed Shaft: Provides a secure connection between the motor shaft and the driven load (e.g., gearboxes, couplings).
