What motors do you manufacture?+
We manufacture 34 series and thousands of specifications including high-voltage motors (6kV/10kV), high-efficiency motors (YE3/YE4/YE5), explosion-proof motors, low-voltage high-power motors, DC motors and synchronous motors, exported to dozens of countries.
Can motors be customized?+
Yes. Non-standard voltage, speed, mounting and VFD support can be customized; please discuss with our engineers.
How can I select a motor quickly?+
Use the "AI Selector" on our website by entering power, voltage and environment; the system recommends from real product data. You may also call our hotline for one-on-one support.
What about warranty and after-sales service?+
We provide full pre-sale selection, in-sale tracking and after-sales service with rapid response via national branches; warranty terms follow the contract.
How do I get a quotation?+
Please call 177-9186-6772 or leave a message on the Contact page; we will quote as soon as possible.
Which energy-efficiency standards do your products meet?+
Products meet GB 18613 national standards, covering IE3/IE4/IE5 premium efficiency grades.
Where is your factory? Can we visit?+
Our factory is in SIMO Motor Industrial Park, Xi'an. Visits are welcome; please call ahead to arrange.
What is the typical lead time?+
Stock models ship quickly; custom orders follow the contract schedule.
Can you do OEM?+
Yes, OEM branding and customized development are supported.
Can HV motors be used with VFDs?+
Yes. We offer HV motors engineered for VFD duty (YJTKK/YJTKS/YJTFKK) and can advise on retrofits.
Which explosion-proof grades do you offer?+
We offer common Ex types across 380V–10kV; choose per your hazardous-area classification.
Are PM motors more energy-efficient?+
PM motors offer higher efficiency and power factor under many loads; a per-application evaluation is recommended.
Do you accept trade-ins or recycling of old motors?+
Yes, we can evaluate trade-ins and recycling; please call to discuss.
What is the warranty period?+
Warranty follows the contract; we respond quickly to quality issues within the warranty period.
Do you provide installation and commissioning?+
Yes, guidance and on-site support are available for large projects.
Where can I buy motor parts?+
Contact us directly for genuine parts to ensure correct fit and quality.
How to verify authenticity?+
Buy through official channels and check the nameplate and certificate; call us to verify if in doubt.
DC or AC motor?+
DC suits wide smooth speed control; AC is simpler and easier to maintain for general drives.
Is an oversized motor wasteful?+
Running far below rated load reduces efficiency; size to the actual load.
Must VFD motors use an inverter?+
Designed for VFD duty, they perform best with an inverter; line operation is possible but without speed control.
What does IP55 mean?+
First digit: solid protection; second: water protection. IP55 is dust-protected and water-jet protected.
Do high-altitude sites need special motors?+
Above 1000m, derating or plateau-specific design is needed; state the altitude when selecting.
Why is my motor noisy?+
Common causes: bearing issues, blocked air ducts, resonance or loose foundations.
How to handle excessive vibration?+
Check foundations and bolts, then rotor balance and bearings; rebalance or replace bearings if needed.
Synchronous vs induction motors?+
Induction motors are simpler and most common; synchronous motors run at exact synchronous speed with higher efficiency, ideal for large constant-speed drives.
What info is needed for a quote?+
Power, voltage, poles, duty, environment and quantity; mention special conditions for accurate pricing.
