Overview

The Techtop XR3-AL-TF-112MB35-2-B-D-7.5 is a high-efficiency, three-phase induction motor designed for industrial applications requiring reliable performance and energy savings. Rated at 7.5 HP (5.5 kW) with a 112MB35 metric IEC frame, this motor delivers 2910 RPM at full load under standard conditions (40°C ambient, 1000m altitude). It operates at dual voltages (190/380V, 50Hz) with a service factor of 1.15, ensuring consistent output even under variable load conditions. Key electrical specifications include a rated current of 20.6A (190V) / 10.3A (380V), nominal efficiency of 89.2% (IE4/NEMA Premium equivalent), and a power factor of 0.91. The motor features a TEFC (Totally Enclosed Fan-Cooled) enclosure with IP55 rating, providing protection against dust ingress and water jets. Tropicalization ensures durability in humid or corrosive environments, while Class H insulation allows for a temperature rise of 53°C at full load. Mechanical robustness is built-in with sealed bearings (6306ZZ DE side, 6206ZZ NDE side), shaft grounding to mitigate bearing currents, and a graphite grey 7024 coating for corrosion resistance. The motor includes M25 x 1.5 cable entry points and is designed for continuous duty (S1). Certified to UL, CSA, and DOE standards (File Nos. 323353, 224693, 096A), it meets Class 1, Division 2 hazardous location requirements. Applications include pumps, fans, compressors, conveyors, and industrial machinery where energy efficiency and reliability are critical. The motor’s dual-voltage compatibility simplifies integration into existing systems, while its compact 112 frame size optimizes space utilization. With a weight of 74.6 lbs and NEMA Design B performance, it delivers high starting torque (8.04 ft-lb) and stable operation across load variations from 50% to 125% of full load. Ideal for OEMs and end-users seeking a high-efficiency, low-maintenance motor with proven certifications and robust construction.
