The OJAM0885 NBD520011A is a 18.5 kW standard squirrel cage induction motor featuring a 4-pole design and an ND180M frame size. Engineered for continuous S1 duty, it operates on a 415 V, 60 Hz stator supply voltage in a delta winding connection with a combined variation of +/-10%. Protected by an IP55 TEFC enclosure, this B3 horizontal foot-mounted motor utilizes Class F insulation with an epoxy gel coat on the winding overhang and a 70 °C temperature rise by resistance method. Designed for an ambient temperature of up to 50°C, it incorporates stainless steel hardware, a full neoprene gasket, and is painted in ACP 631 Light Grey using a C3-M painting procedure. It features Direct On Line starting, bidirectional rotation viewed from the drive end, a right-hand terminal box position from the drive end, and a standard shaft extension. Noise and vibration levels comply with IEC 60034-9 and IEC 60034-14 Grade A standards respectively, conforming to IEC60034.
