Product Characteristics
Standardized IEC Small Frame Series
Fully compliant with IEC60072 international standard, complete small frame sizes including 63/71/80.ect Uniform shaft height, mounting feet, flange and output shaft dimensions with compact lightweight die-cast aluminum housing for strong interchangeability during replacement.
Symmetric 3-Phase Windings Without Starting Capacitors
Three groups of 120° symmetric windings generate natural rotating magnetic field from three-phase power for self-starting. No start or run capacitors required, simplifying internal wiring and eliminating capacitor failure risks of single-phase motors.
Class F Insulation & IP55 Totally Enclosed TEFC Construction
Windings use heat-resistant Class F enameled wires to resist thermal aging and temperature rise. Totally enclosed fan-cooled housing reaches IP55 dust and splash-proof grade, delivering stable long-term performance in dusty and humid small processing workshops.
Product advantages
Strong Starting Torque & High Operation Efficiency
Balanced three-phase magnetic field delivers steady sufficient torque for smooth heavy-load startup. It boasts higher energy efficiency than single-phase motors of the same frame size, cutting power consumption and electricity cost during continuous full-load production.
Low Failure Rate & Minimal Maintenance
Free of vulnerable wearing parts like centrifugal switches and capacitors for enhanced durability. It generates less vibration and running noise, only simple fan cover dust cleaning is needed to lower maintenance frequency.
Wide Compatibility for Various Loads
Linear and stable power output fits light and medium loads such as fans, water pumps and light machine tools, supporting 24-hour S1 continuous duty cycle reliably.

FAQ
Q: Is a frequency converter mandatory for small IEC three phase motors?
A: No, it runs at fixed speed directly connected to standard 380V 3-phase mains supply. A matching power inverter is only required if variable speed control is needed.
Q: Can a small three phase motor of the same frame replace an original single phase motor directly?
A: The mounting dimensions are interchangeable, but the power circuit needs to be rebuilt for three-phase power; it cannot be driven by original 220V single-phase wiring.
Q: Can IP55 small three phase motors operate long-term in damp basements?
A: It resists dust and splashing water, yet ventilation and dehumidification are recommended for basements with constant condensate or accumulated water to prevent premature shaft seal aging.
