Raydafon YS/YE2/YE3 three-phase asynchronous motors cover 0.12–355 kW with IE2/IE3 efficiency, IP54/IP55 protection, F-class insulation and B3/B5/B35 mounting. Choose YE2 for IE2, YE3 for IE3, YEJ2 for fail-safe brake duty and YVF2 for VFD operation. Custom voltage, frequency, shaft and nameplate available for OEM buyers.
YS/YE2/YE3 Three-Phase Asynchronous Motor for OEM Industrial Drives
Raydafon builds IE2 and IE3 induction motors from 0.12 kW to 355 kW, with cast-iron frames, F-class insulation, IP54/IP55 protection and B3/B5/B35 mounting. Brake and VFD versions are available for conveyors, hoists, pumps, fans and production lines.
YE2 and YE3 cover general industrial drive duties. YEJ2 adds fail-safe electromagnetic braking for conveyors, hoists and packaging lines. YVF2 is built for inverter duty with forced ventilation, so it can hold cooling at low speed.
YE2 Series
IE2 high-efficiency motor per GB18613 Level 3 and IEC 60034-30 IE2. Suitable for fans, pumps, compressors, machine tools and general machinery.
YE3 Series
IE3 premium efficiency motor with lower losses. Ideal for continuous duty where energy cost reduction matters.
YEJ2 / YDEJ2 Series
Electromagnetic DC brake motor with fail-safe stopping on power loss. Brake response 0.15–0.45 s no-load.
YVF2 Series
VFD-ready motor with IC416 forced ventilation and stepless speed regulation from 150 to 2750 rpm.
0.12–355 kWPower range across YS/YE2/YE3/YEJ2/YVF2 series
71–355 mmFrame size range for small machinery to heavy industrial drives
IP54 / IP55Protection grade with cast-iron housing and F-class insulation
B3 / B5 / B35Foot, flange and foot-flange mounting configurations
Technical Specifications
Standard rated voltage is 380V / 50Hz. Custom voltage, frequency, shaft, thermal protection, IP rating and nameplate branding are available for OEM projects.
These motors are used where reliable torque, continuous duty and low maintenance are required. Brake and VFD versions solve stopping, holding and speed-control duties in the same footprint.

Frequently Asked Questions
These answers help engineers and buyers compare IE2, IE3, brake and VFD motor options before requesting a quotation.
What is the difference between IE2 and IE3 efficiency?
IE3 motors are approximately 2–5% more efficient than IE2, resulting in lower energy consumption and reduced CO₂ emissions over the motor lifetime.
Can I use a standard motor with a variable frequency drive?
Standard motors may overheat at low speeds. We recommend the YVF2 series, which is specifically designed for VFD operation with forced cooling IC416.
What is the brake response time on YEJ2 motors?
The no-load braking time ranges from 0.15 to 0.45 seconds depending on frame size. Brake power must be synchronised with motor power.
Do you offer motors with different voltage or frequency?
Yes. We can customise voltage such as 220V, 400V and 460V, and frequency 50Hz or 60Hz to meet local power supply requirements.
What is the warranty period?
We provide an 18-month warranty from date of shipment, covering manufacturing defects, with full technical support.
