  • How to select the right motor (e.g., three-phase asynchronous motor, explosion-proof motor) for my application?
    A: Key steps for motor selection: Confirm core parameters: power, speed, voltage (380V/440V), frequency (50Hz/60Hz). Match working conditions: explosion-proof grade (Ex d IIB T4/T6 for hazardous areas), protection class (IP54/IP65 for dust/water resistance), temperature range (-20℃~40℃ typical). Consider application scenarios: pumps/fans (focus on efficiency), conveyors (focus on torque), industrial machinery (focus on stability). Provide your working conditions, we’ll recommend a cost-effective model or alternative (e.g., ABB/Siemens equivalent).
  • Can you provide customized motor solutions for special requirements?
    Yes, we offer flexible customization services: Customizable parameters: power (0.55kW~1000kW), speed (500rpm~3000rpm), mounting type (B3/B5/B35), shaft size. Special modifications: explosion-proof design, high-temperature resistance (up to 150℃), low-noise (≤75dB), energy-saving upgrade (IE3/IE4 efficiency). Lead time: 7~15 working days for standard customization; 15~30 days for complex modifications. Process: Submit requirements → technical evaluation → quotation → sample confirmation → mass production.
  • What should I pay attention to during motor installation?
    Key installation guidelines (with after-sales support): Pre-installation check: Inspect motor appearance, confirm voltage/frequency matches the power supply. Installation requirements: Align motor and load (concentricity error ≤0.1mm), ensure stable base fixation, proper ventilation (clearance ≥10cm around). Wiring: Follow the wiring diagram (3-phase Y/Δ connection), ensure tight terminals and reliable grounding (PE wire). Post-installation test: No-load operation for 30 minutes, check temperature (≤80℃) and noise. Support: Provide installation manual (English/Chinese); technical team available for on-site guidance (domestic cities: 24~48h response).
  • What efficiency classes do your motors comply with, and how does it affect operation costs?
    High-efficiency motors for cost savings: Compliance: IE3 (premium efficiency) as standard, IE4 (super premium) optional for energy-saving needs. Benefits: IE3 motors reduce energy consumption by 10~15% vs. IE2, cutting annual electricity costs significantly for long-term operation. Certification: CE/UL/TUV approved, meeting international energy efficiency standards (GB 18613-2020, IEC 60034-30-1). Recommendation: Provide your daily operating hours and power demand, we’ll calculate energy-saving potential for you.
  • What is your warranty policy and after-sales support for motors?
    Reliable warranty and responsive support: Warranty period: 12 months from delivery (or 15,000 operating hours, whichever comes first) for standard/customized motors. Coverage: Free repair/replacement for manufacturing defects (excluding damage from improper use or natural disasters). After-sales service: Shanghai-based technical team, 24h online consultation; on-site maintenance within 48h for domestic clients, 72h for major cities in Asia. Spare parts: Stocked key components (bearings, windings) for quick replacement, ensuring minimal downtime.
  • What is your delivery time and logistics arrangement from Shanghai?
    Fast delivery and reliable logistics: Standard models: In stock, delivery within 3~5 working days after payment. Customized models: As per confirmed lead time (7~30 working days). Logistics options: Door-to-door delivery via Sinotrans/COSCO; urgent orders via air freight (Shanghai Pudong Airport). Packaging: Seaworthy wooden cases with moisture-proof and shock-proof protection, suitable for domestic/international shipping. Tracking: Provide logistics number for real-time status inquiry.
  • Can you provide replacement motors for ABB/Siemens models, and what are the advantages?
    Cost-effective alternatives to top brands: Compatibility: Support replacement for ABB M2BAX, Siemens 1LE1 series (three-phase asynchronous/explosion-proof motors). Key advantages: Same installation dimensions (mounting type, shaft size) for direct swap; 10~20% lower price vs. original brands; equivalent efficiency (IE3/IE4) and reliability. Matching process: Provide your existing motor model (e.g., ABB M2BAX 132SMA4) → technical matching → sample testing (optional) → bulk supply. Quality guarantee: Strict quality control (ISO 9001 certified) to ensure performance consistency with original brands.
  • What regular maintenance is required for motors to extend their service life?
    Simple maintenance guidelines for long durability: Routine checks: Monthly inspect wiring terminals (tightness), bearing temperature (≤85℃), and fan operation (no blockage). Lubrication: Replace bearing grease every 6~12 months (depending on operating hours; use high-temperature grease for special models). Cleaning: Remove dust/debris from motor surface and ventilation holes quarterly to avoid overheating. Storage: For idle motors, keep in dry environment (humidity ≤60%), rotate shaft monthly to prevent bearing seizing. Support: Provide detailed maintenance manual; technical team available for on-site training if needed.
