Simo Motor Selection Guide: A Comprehensive Analysis of Frequently Asked Questions

Basic Parameters Selection Guide

What are the fundamental parameters to consider when selecting an electric motor?

When selecting a model, the following core parameters must be confirmed:

• power (output)Calculate the required power based on the load, leaving a 10-15% margin.
• voltage level380V, 660V, 6kV, 10kV, etc., requiring matching power supply systems
• Rotational Speed RequirementsSelect 2-pole, 4-pole, 6-pole, etc., according to equipment process requirements.
• protection classIP54, IP55, etc., determined based on the operating environment.
• InstallationB3 (horizontal), B5 (vertical), etc.

How to calculate the required motor power?

Power calculation formula:

text

Power (kW) = Torque (N·m) × RPM (rpm) / 9550

We recommend providing equipment parameters for calculation assistance by the Xima technical team.

Application Scenario Selection Guide

How to Select Motor Types for Different Industries?

• Fans and Pumps：Select Y/YS series high-efficiency motors
• Mining Machinery：Select YRWire-wound motorsHigh starting torque
• petrochemical industry：SelectExplosion-proof motorsThe level must match the hazardous area.
• Metallurgical industry：Select YZR metallurgical crane motors, high-temperature resistant

How to select equipment for special environments?

• humid environment：Select H-class insulation, IP55 or higher protection rating
• high temperature environmentSelect F/H-class insulation, considering high-temperature bearings.
• Corrosive environment：Stainless steel material or special surface treatment
• Explosion-proof requirementsSelect the corresponding explosion-proof rating based on the explosive atmosphere classification.

Technical Specifications Explained

How should energy efficiency ratings be selected?

• IE2：For general purposes
• IE3Highly efficient and energy-saving, recommended for selection.
• Internet Explorer 4: Ultra-efficient, more economical for long-term operation
• Simo motorsThe entire series meets IE3 and higher energy efficiency standards.

What does the motor's protection rating represent?

• IP54Dustproof and splash-proof, suitable for indoor environments
• IP55Dustproof and splash-proof, suitable for outdoor environments
• IP56Dustproof, resistant to powerful water jets
• IP65Dust-tight and splash-proof, suitable for harsh environments

Compatible Model Selection Guide

How to select the appropriate starting equipment?

• Direct Start：Suitable for low-power motors (≤75kW)
• Star-Delta Starting：Suitable for medium power applications, reducing inrush current
• Soft StarterSmooth start-up, protecting equipment
• Frequency Converter: Applications requiring variable speed control

How should the connection method between the motor and equipment be selected?

• Flexible coupling：Allow for a certain degree of misalignment error
• Belt driveSituations requiring gear shifting
• Direct connection：Highest efficiency, requires precise alignment

Selection Considerations

What are common pitfalls in product selection?

• Power selection is too high: resulting in reduced efficiency and increased costs
• Ignore startup characteristics: Causing grid impact or startup failure
• Ignore environmental factorsFactors Affecting Motor Service Life
• Insufficient protection rating: leading to premature motor failure

How can you verify whether the selection is appropriate?

Please provide the following information for review by Xima engineers:

1. Equipment Types and Working Principles
2. Load characteristic curve
3. Operating Environment Conditions
4. Control Method Requirements
5. Existing Power Supply System Parameters
