Overview

The Techtop GR3-AL-TF-71B34-4-B-D-.75 is a 0.75 HP IEC metric three-phase motor designed for industrial applications requiring reliable, energy-efficient operation. This motor features a 71B34 frame size, 4-pole configuration (1720 RPM at full load), and dual-voltage compatibility (208-230/460V at 60Hz). The Totally Enclosed Fan-Cooled (TEFC) design ensures robust protection against dust and moisture, making it ideal for harsh industrial environments. Key specifications include an IE3 efficiency rating of 81.5%, NEMA Design B performance, and a service factor of 1.15. The motor operates at a rated ambient temperature of 40°C and has a temperature rise of 21.1°C at full load. Electrical data includes a rated current of 2.75-2.50/1.25 Amps (high/low voltage) and a locked rotor current of 6.11 Amps. Mechanical data includes 6202ZZ bearings on both the drive end (DE) and non-drive end (NDE) sides, a cable entry size of M20 x 1.5, and a graphite grey coating (7024). The motor has a full load torque of 2.28656 ft-lb and a breakdown torque of 328% of full load torque. The approximate weight is 18.64 kg, and the motor is rated for altitudes up to 1000 meters. Applications include conveyor systems, pumps, fans, compressors, and material handling equipment. The motor’s 4-pole design provides balanced torque and speed for continuous-duty cycles. The dual-voltage capability simplifies inventory management and reduces the need for multiple motor variants. The TEFC enclosure protects internal components from contaminants, extending operational lifespan in demanding conditions.
