IEC Metric

IEC Metric Motors (TEFC) are designed and built according to European IEC34 and IEC79 standards.

Features that make a difference:

• 1.25 service factor for 60 HZ operation (IE3)
• 1.15 service factor for 60 HZ operation (IE2)
• Optimized ventilation system for cooler operation and reduced noise levels
• Solid base for reduced vibration levels (Cast iron frames)
• Frames 225 & up can easily be F1 (B3L) converted by simply rotating the terminal box adapter or F3 by removing it
• Aluminum frames have removable feet for easy F1, F2 and F3 (B3L, B3R, B3T) conversion
• Terminal blocks
• Class F insulation (Impregnation resin and magnet wire are Class H)
• F2 mounted as standard (F1 convertible)
• Regreasable ball bearings (Frames 160 and up)
• Class 1, Div. 2, Groups A, B, C & D – T3, Class 2, Div. 2, Groups F & G – T3C (Cast iron frames only)
• Suitable for WYE/Delta Start (W and Y voltage code motors)

Inverter Rated (IE3):

• 1000 : 1 for variable torque
• 12 : 1 constant torque

Inverter Rated (IE2):

• 10 : 1 for variable torque
• 4 : 1 constant torque
