What is 3 Phase AC Motor?

Three-phase asynchronous motor is a commonly used AC motor. It consists of two parts: the stator and the rotor. The stator generates a rotating magnetic field. The rotor generates an induced current under the action of the rotating magnetic field and rotates under the action of the electromagnetic force.
Three-phase asynchronous motor is widely used in industry, agriculture, transportation and other fields, is the main power source to drag a variety of mechanical equipment.

Difference of IEC standard and NEMA standard

Difference of IEC standard and NEMA standard
Difference	IEC	NEMA
Size standard	Metric system	American market/inch (including terminal box outlet thread holes)
Global market share	70%	30%
Enforce standards	EC60034, 60071	Nema MG1
Common case	Cast aluminum or cast iron	Cast iron or cast steel
Common class of protection	IP44 and above	IP20 and above
Common bearing greases	Lithium base grease	Polyurethane base grease
Common motor junction box locations	upper	Left or right side
Motor seal	Sealing ring (higher)	Common splash ring seal (lower)/ high seal ring
Motor drainage	No explicit requirement	A drainage hole or vent hole is commonly required
Motor starting current and torque	EC-N/NE/H/HE IEC-N≈Nema A/B EC-H≈Nema C	Nema A, B, C, D [Common nema B] The starting current and starting torque are specified. As ABCD rises, the current increases and the starting torque increases. Nema D has no corresponding IEC standard.
Frequency	50HZ	60HZ
wiring	Common 6-post patch panel (star angled)	Common 9-post patch board (Double star connection)
Allowable supply voltage deviation	Zone A ±5%, zone B ±10%	Standard ±10%
Allow power supply frequency deviation	Zone A ±2%, zone B +3%~ -5%	Frequency ±5% at rated voltage
Motor duty system	More detailed definition, S1... S10	Slightly simpler definition
Motor overload capacity	Standard 1.0	Allow 115% overload for a long time (i.e. : factor 1.15)
Energy efficiency test method	IEC60034-2-2 B1 Current EU Access IE3	EEE 112-2017 B CSA390:10 (R2019) Current North American access equivalent to IE3
Insulation requirements/certifications	Low/common CE	High insulation requirements, special stator /(UL/CSA)

Overall, NEMA's philosophy emphasizes more robust design for wider applicability, while IEC focuses on application and performance. There is little fundamental difference between the two motor standards and they can be used interchangeably.

More Cases

Production Process From 3 Phase AC Motor Factory

1.Check motor specification according to production sheet.

5.Assemble the stator coil, rotor shaft, frame, fan and cover, etc. into finished motors, and energized to test whether they can work normally.

2.Prepare raw material：Copper wire, stator, rotor, frame...

6.Paint the motors, and check appearance.

3.Machine shaft by automatic lathe, and measure the dimensions again by hand.

7.Put the motor in a dust-proof bag, wrap in anti-collision cotton and put in a wooden box.

4.Wind the copper coil, and measure the performance one by one on the test equipment.
