Question 1

What motors do you manufacture?

Accepted Answer

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.

Question 2

Can motors be customized?

Accepted Answer

Yes. Non-standard voltage, speed, mounting and VFD support can be customized; please discuss with our engineers.

Question 3

How can I select a motor quickly?

Accepted Answer

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.

Question 4

What about warranty and after-sales service?

Accepted Answer

We provide full pre-sale selection, in-sale tracking and after-sales service with rapid response via national branches; warranty terms follow the contract.

Question 5

How do I get a quotation?

Accepted Answer

Please call 177-9186-6772 or leave a message on the Contact page; we will quote as soon as possible.

Question 6

Which energy-efficiency standards do your products meet?

Accepted Answer

Products meet GB 18613 national standards, covering IE3/IE4/IE5 premium efficiency grades.

Question 7

Where is your factory? Can we visit?

Accepted Answer

Our factory is in SIMO Motor Industrial Park, Xi'an. Visits are welcome; please call ahead to arrange.

Question 8

What is the typical lead time?

Accepted Answer

Stock models ship quickly; custom orders follow the contract schedule.

Question 9

Can you do OEM?

Accepted Answer

Yes, OEM branding and customized development are supported.

Question 10

Can HV motors be used with VFDs?

Accepted Answer

Yes. We offer HV motors engineered for VFD duty (YJTKK/YJTKS/YJTFKK) and can advise on retrofits.

Question 11

Which explosion-proof grades do you offer?

Accepted Answer

We offer common Ex types across 380V–10kV; choose per your hazardous-area classification.

Question 12

Are PM motors more energy-efficient?

Accepted Answer

PM motors offer higher efficiency and power factor under many loads; a per-application evaluation is recommended.

Question 13

Do you accept trade-ins or recycling of old motors?

Accepted Answer

Yes, we can evaluate trade-ins and recycling; please call to discuss.

Question 14

What is the warranty period?

Accepted Answer

Warranty follows the contract; we respond quickly to quality issues within the warranty period.

Question 15

Do you provide installation and commissioning?

Accepted Answer

Yes, guidance and on-site support are available for large projects.

Question 16

Where can I buy motor parts?

Accepted Answer

Contact us directly for genuine parts to ensure correct fit and quality.

Question 17

How to verify authenticity?

Accepted Answer

Buy through official channels and check the nameplate and certificate; call us to verify if in doubt.

Question 18

DC or AC motor?

Accepted Answer

DC suits wide smooth speed control; AC is simpler and easier to maintain for general drives.

Question 19

Is an oversized motor wasteful?

Accepted Answer

Running far below rated load reduces efficiency; size to the actual load.

Question 20

Must VFD motors use an inverter?

Accepted Answer

Designed for VFD duty, they perform best with an inverter; line operation is possible but without speed control.

Question 21

What does IP55 mean?

Accepted Answer

First digit: solid protection; second: water protection. IP55 is dust-protected and water-jet protected.

Question 22

Do high-altitude sites need special motors?

Accepted Answer

Above 1000m, derating or plateau-specific design is needed; state the altitude when selecting.

Question 23

Why is my motor noisy?

Accepted Answer

Common causes: bearing issues, blocked air ducts, resonance or loose foundations.

Question 24

How to handle excessive vibration?

Accepted Answer

Check foundations and bolts, then rotor balance and bearings; rebalance or replace bearings if needed.

Question 25

Synchronous vs induction motors?

Accepted Answer

Induction motors are simpler and most common; synchronous motors run at exact synchronous speed with higher efficiency, ideal for large constant-speed drives.

Question 26

What info is needed for a quote?

Accepted Answer

Power, voltage, poles, duty, environment and quantity; mention special conditions for accurate pricing.
