Product Description
The Nord SK80L/4 CUS56CBRE20FHLRGIR is a 4-pole, three-phase inverter/vector duty AC motor built on Nord's IEC 80L frame with a NEMA 56C C-face adapter for direct coupling to standard NEMA gearboxes and drives. It is equipped with a BRE20 spring-set electromagnetic brake (20 Nm braking torque) featuring a Locking Manual Hand Release (FHL), a corrosion-protected stainless steel brake plate (RG), and a Current Sensing Relay (IR) for brake monitoring. The motor is rated 0.75 kW (1 HP) at 1650 RPM on 230/460V, 60 Hz, and carries IP55 enclosure protection with Class F insulation for demanding industrial environments. The squirrel cage induction design features a single keyed shaft (19 mm / 0.75 in diameter), NEMA Design B characteristics, and moisture-resistant varnish-dipped windings suitable for inverter and vector drive applications per NEMA MG1 Section 31.4.4.2.
