Below is your precise converted value, mathematical formula, and motor frame equivalent.
This unit converter provides exact mathematical conversions and standard motor frame equivalents for budgeting and engineering specification. When replacing electric motors or gearboxes, physical shaft dimensions, keyways, and flange mounting holes must be verified against the manufacturer's dimension drawing (SEW Eurodrive, AC Motoren, Siemens). Mega Standard accepts no liability for decisions made on these figures alone.
Conversion factors are based on international standards: 1 kW = 1.34102 HP, 1 bar = 14.5038 psi, 1 Nm = 0.737562 ft-lb. Motor frame cross-references assume standard 4-pole 1500 RPM / 1800 RPM induction motors.
Procurement engineers in Iraq frequently deal with machinery imported from both Europe (metric IEC standards) and the USA / Asia (imperial NEMA standards). Converting power, pressure, and frame dimensions accurately prevents costly fitting errors on site.
IEC Frame Number: Directly represents the shaft center height $H$ in millimeters. For example, an IEC 112M motor has a shaft height of exactly 112 mm.
NEMA Frame Number: The first two digits divided by 4 equal the shaft height $D$ in inches. For example, a NEMA 184T motor has a shaft height of $18 / 4 = 4.5$ inches ($114.3$ mm).
Exact conversion constants used by ISO 80000:
Power: 1 kW = 1.34102 HP (mechanical)
1 HP = 0.745700 kW
Pressure: 1 bar = 14.5038 psi = 100 kPa
1 psi = 0.0689476 bar = 6.89476 kPa
Torque: 1 Nm = 0.737562 ft-lb
1 ft-lb = 1.355818 Nm
When selecting replacement motors, always ensure the motor frame size, shaft diameter, and keyway dimensions match the driven machine's coupling.
Multiply the kW rating by 1.341. For example, a 22 kW motor equals 22 × 1.341 = 29.5 HP, which corresponds to a standard 30 HP motor rating.
An IEC 132S/M motor (shaft height 132 mm) corresponds closely to NEMA 213T / 215T (shaft height 133.35 mm / 5.25 inches).
We supply genuine SEW Eurodrive gearmotors, AC Motoren (Germany) IEC aluminum and cast iron 3-phase motors, and Siemens motors from our warehouse in Kirkuk.
Iraq's national electrical grid operates at 50 Hz. Motor synchronous speed is $N = 120 imes f / P$. A 4-pole motor runs at 1500 RPM at 50 Hz, compared to 1800 RPM at 60 Hz.
We supply SEW Eurodrive gearmotors, AC Motoren (Germany) 3-phase electric motors, and Siemens motors across Iraq. Stocked in Kirkuk from 0.18 kW to 200 kW.
