Oriental Motor 90W Reversible AC Motor (5RK90GE-CW3)
The Oriental Motor 5RK90GE-CW3 is a high-performance 90W (1/8 HP) AC motor engineered specifically for applications requiring frequent and instantaneous directional changes.1 Unlike standard induction motors, reversible motors feature a built-in friction brake mechanism that minimizes overrun and allows for rapid switching between clockwise and counter-clockwise rotation.2
This Pinion Shaft model is designed to be paired with a gearhead, allowing you to customize the output speed and torque to meet your specific automation needs.3
Key Performance Features
Instantaneous Reversibility: Optimized for high-cycle applications where the motor must stop and reverse directions immediately.
High Torque Density: Provides a robust 90W of output power in a compact frame size, ideal for space-constrained industrial machinery.
inion Shaft Design: Integrated pinion allows for seamless mounting to Oriental Motor “GE” type gearheads for significant torque multiplication.
Thermal Protection: Rated for Class B insulation (130C), ensuring reliability during continuous or high-frequency operation.
Lead Wire Connection: Features a simple lead wire configuration for straightforward integration into control panels.
