SEW-EURODRIVE Right-Angle Helical-Bevel Gearmotor Assembly, combining a high-efficiency DRN-series AC motor with a KT47 gear reducer.

• Technical Specification BreakdownGearbox Series (KT47): A right-angle helical-bevel gearbox configuration. The "K" signifies a multi-stage helical-bevel design known for high mechanical efficiency, "T" usually indicates a hollow shaft design with a torque arm, and "47" designates the physical frame size of the gearbox.
• Motor Model (DRN90L4): SEW-Eurodrive's premium efficiency asynchronous AC motor line. "90L" specifies the motor frame size, and "4" indicates a 4-pole design.
• Speed Dynamics (1767 / 269 RPM): The motor runs natively at an input speed of 1767 RPM. After passing through the gearbox reduction ratio (approximately 6.57:1), the final output shaft speed scales down to 269 RPM.
• Power & Electricals: Rated at 2 Horsepower (HP), configured for a three-phase system with dual-voltage capability. It draws 6 Amps at 230V or 3 Amps when wired for 460V.
• Duty Cycle (CONT S1): Rated for Continuous Duty (S1), meaning the motor can operate indefinitely under its maximum specified load without needing rest periods to cool down.
• Torque Rating: Yields 2120 in-lbs of continuous output torque at the output shaft.
• Inverter Duty (VPWM): Engineered with an insulation system designed to handle the voltage spikes and thermal demands of running on a Variable Frequency Drive (VFD) using Voltage-source Pulse Width Modulation (VPWM) control.

The SEW-EURODRIVE gear motor, model KT47 DRN90L4, combines a high-efficiency DRN-series AC motor with a KT47 right-angle helical-bevel gearbox. This gear motor outputs at speeds ranging from 1767 RPM to 269 RPM, powered by a 2HP motor. It is designed for dual-voltage operation at 230V and 460V, drawing 6 Amps and 3 Amps respectively. Built with continuous duty (S1) in mind, it can continuously operate under its maximum load without the need for rest periods. The gearbox features a multi-stage helical-bevel design, providing efficient power transmission with a torque output of 2120 in-lbs. Furthermore, it is equipped for inverter duty using Voltage-source Pulse Width Modulation (VPWM), ensuring durability and performance when integrated with Variable Frequency Drives (VFD). Overall, this gear motor from SEW-EURODRIVE is a reliable and efficient solution for industrial applications requiring robust and continuous performance.
