How to Select the Correct YE3 Motor
- Define the driven load: confirm the machine type, required shaft power, starting condition and daily operating duty.
- Confirm the electrical supply: provide voltage, frequency and available starting method before selecting a motor winding.
- Choose poles or target speed: select 2P, 4P or 6P from the required motor speed; when a reducer is used, confirm the gearbox ratio and target output speed together.
- Check the mechanical interface: verify frame size, shaft diameter, mounting arrangement and the motor flange required by the machine or gearbox.
- Confirm the environment: state the required protection class, ambient conditions, installation orientation and whether a brake is needed.
Configuration limit: Not every power, frame, shaft, voltage, frequency, pole, mounting and protection option can be combined freely. Final rated current, rated speed, dimensions and compatibility must be confirmed from the selected motor configuration and application.
Motor and Gearbox Matching
For a complete geared drive, provide required output speed and load torque in addition to the motor data. Compare matched gear motor options, review the NMRV worm gearbox range, or use the three-phase motor selection guide.

YE3 Electric Motor FAQ
Selection answers for SMK YE3 industrial AC motors.
What is the listed power and voltage range?
The YE3 motor range shown on this page is 0.06 to 7.5 kW, approximately 1/12 HP to 10 HP, for 220/380V configurations subject to final technical confirmation.
What frame sizes and shaft diameters are available?
The listed frame sizes are H56 to H132 and the listed shaft diameters are Φ9 to Φ38. The exact shaft and mounting dimensions depend on motor frame and configuration.
Which frequencies and pole options are available?
The listed frequency options are 50 Hz and 60 Hz, with 2-pole, 4-pole and 6-pole options. Rated speed depends on frequency, pole count and motor design.
What information is needed for an electric motor quotation?
Please provide required power, voltage, frequency, poles or target speed, mounting arrangement, protection class, duty, application and quantity.
Can every power rating use every frame size and mounting arrangement?
No. Power, frame size, shaft diameter, mounting arrangement, voltage, frequency, pole count and protection class must be confirmed as one compatible motor configuration for the application.
What manufacturing and compliance information is available?
SMK supports motor and gearbox matching through its Jiangsu production operation. Compliance documentation is available for applicable models and orders upon request; the exact document set must be confirmed before purchase.
