 High-performance SEW-EURODRIVE Right-Angle Helical-Bevel Gear Motor assembly. Here is a complete technical breakdown of what each part of that model string and specification plate means

• Model & Component NomenclatureKT37 (Gear Unit): This designates a three-stage Helical-Bevel right-angle gearbox. The "K" series is highly valued for its high efficiency (typically over 90% in both directions) and high wear resistance compared to standard worm gears.
• AM145 (Input Adapter): This represents a modular NEMA flange adapter. It allows a standard NEMA 145TC frame motor to be mounted directly onto the KT37 gearbox.
• DRN90L4 (AC Motor): This is the specific asynchronous AC motor model.DRN: SEW's high-efficiency motor line (Premium Efficiency / IE3 equivalent).
• 90L: The physical frame size configuration of the motor.
• 4: Designates a 4-pole motor, which inherently runs at a base synchronous speed of 1800 RPM on a 60 Hz grid (dropping slightly to an actual full-load speed of around 1767 RPM).
• Performance Specifications1767 / 115 RPM: 1767 RPM is the input speed of the motor itself at full load. 115 RPM is the final output speed coming out of the gearbox shaft after gear reduction. (This indicates a gear reduction ratio of roughly 15.36:1).
• 2 HP: The motor provides 2 Horsepower of mechanical output power.
• 208-230/460 V: A dual-voltage configuration. It can be wired for low-voltage (208V to 230V) or high-voltage (460V) industrial 3-phase power grids.
• DUTY CONT S1: Rated for Continuous Duty. The motor can operate indefinitely under its rated load conditions without exceeding its thermal limitations.
• MAX TORQUE 1550 IN LBS: The internal gearbox components and output shaft are physically rated to handle up to 1,550 inch-pounds of continuous torque before risking mechanical damage.

The SEW-EURODRIVE Gear Motor Model KT37 AM145 DRN90L4 is a high-performance right-angle helical-bevel gear motor designed for efficiency and durability. It features a three-stage helical-bevel gearbox, providing a gear reduction ratio of approximately 15.36:1. The motor runs at an input speed of 1767 RPM, delivering an output speed of 115 RPM and generating a maximum torque of 1550 inch-pounds. This model is driven by a 2 HP DRN90L4 motor, which is part of SEW's high-efficiency line. Operating on a 208-230/460 V three-phase power supply, the motor offers dual-voltage functionality. It is designed to work continuously under rated load conditions (Duty Cont S1), ensuring reliable performance without overheating. Its standard NEMA flange adapter (AM145) supports easy integration with a variety of industrial systems. The motor's frame size is designated as 90L, and it features a 4-pole configuration, ensuring a stable operating speed. This gear motor assembly demonstrates excellent efficiency over 90% typically, as part of the K series known for high wear resistance. It is suitable for demanding industrial applications where precise and reliable speed and torque is essential. With its robust construction, the SEW-EURODRIVE gear motor offers durability and extended service life.
