Motors that match your needs
ABB synchronous motors deliver efficient and reliable operation
in a wide range of applications. We have a strong track record in tailoring
motors to match customer needs across different industries.
Examples of industries and applications where our motors are operating include:
• Oil, gas and petrochemical: compressors, pumps, fans and extruders
• Marine and offshore: variable speed motors in azimuthing propulsors and shaft line applications
• Metals and minerals: rolling mills, hoists, processing lines, semi-autogenous grinding (SAG) mills, ball
mills and blowers
• Power utilities: pumps, fans and condensers
• Pulp and paper: chippers, refiners and grinders
• Water and wastewater: pumps
• Air separation: compressors
• Specialized applications: wind tunnel motors and motor-generator sets

Testing
Three levels of testing
Each motor is thoroughly tested before it leaves the factory.
—
Three levels of testing
1. Routine tests
• performed on all motors
2. Type tests
• done in addition to routine tests
• normally performed on one motor in a series that has not been previously manufactured
• can also be undertaken at the customer’s request
3. Special tests
• may be conducted to verify performance in special conditions, eg, to verify compliance with
customer specifications regarding noise or vibration
• could also be done with regard to hazardous area or marine classification society requirements
