1. Define Basic Parameters
Power & Speed:
Determine the required rated power based on load characteristics and define the motor pole count and speed range according to your equipment’s operational speed.
Voltage & Frequency:
Confirm your power supply standard (e.g., 380V/50Hz, 480V/60Hz). Custom designs are available for special voltage requirements.
Mounting Type:
Specify IEC standard mounting (e.g., B3, B5, B14). Custom the flanges & bases are also supported.
2. Consider Operating Environment
Protection Rating (IP):
IP55 for standard environments. IP65 is recommended for damp or dusty conditions. Hazardous areas require Ex D/Ex E certifications.
Insulation Class:
Class F (155°C) for general use. Class H (180°C) insulation is advised for high-temperature environments.
Cooling Method:
Self-ventilated (IC411) for standard applications. Forced air or water cooling is available for enclosed spaces or high-power-density scenarios.
3. Match Load Characteristics
Starting Torque:
Consider starting torque for fan/pump loads. Verify locked-rotor torque for conveying equipment.
Duty Cycle:
Standard motors are suitable for continuous operation (S1). Frequent start-stop cycles (S5) require reinforced bearings and insulation.
Efficiency Requirement:
Select IE3/IE4/IE5 efficiency classes based on annual operating hours. Ultra-premium efficiency (IE5) motors offer the lowest total cost of ownership for long-running applications.

Frequently Asked Questions (FAQ)
Q1: What information is needed for one custom motor quote?
Please provide complete operational parameters (load characteristic curve, ambient temperature, altitude), mechanical interface requirements (shaft dimensions, mounting type), electrical specifications (voltage, frequency, control method) and any special needs (explosion-proof rating, certification requirements, noise limits).
Q2: Is investing in an IE5 ultra-premium efficiency motor worthwhile?
For example, the 90kW IE5 motor can save approximately 32,000 kWh annually compared to an IE3 model when running 6,000 hours per year. At the electricity rate of ¥0.8/kWh, the price difference can be recovered within 2 years. For long-running applications, high-efficiency motors significantly reduce your Total Cost of Ownership (TCO).
Q3: What is the standard lead time for motors?
Standard models are typically in stock and can be shipped within 5-7 work days. Custom motors generally require 4-8 weeks, depending on technical complexity. Our MES system provides real-time production updates for complete delivery transparency.
Q4: How do you ensure the motor perfectly matches my equipment?
We offer the three-step assurance process:
Optional on-site inspection by our engineers during the selection phase.
Load testing with a sample motor.
Support for PLM system data integration to enable digital collaboration between motor parameters and your equipment design.
Q5: What is the motor warranty period?
Our standard warranty is 12-24 months from the date of shipment or 10,000 operating hours, whichever comes first. For special applications (e.g., mining, marine), warranties can be extended to 36 months, complemented by full lifecycle health monitoring services. Contact our team for warranty details.
