Worldwide Standard AC Motors
Safety Standards for Safe, Reliable Operation
All World K Series models have a built-in overheat protection device and conform to major international safety standards. UL/CSA, CE Marking (Low Voltage Directive), models certified under CCC (China Compulsory Certification system) are also available.
Motor Overheat Protection Device
Thermal Protector:
A built-in feature of all motors with a frame size of 2.76 in. (70 mm) or more.
Impedance Protection:
Implemented on all motors with a frame size of 2.36 in. (60 mm) or less.
Global Voltage Specifications
The World K Series supports the power supply voltages used in major countries. Motors meeting the local voltage standard are readily available in major countries in Europe, Asia and North America.
The Motor Bearing Life is Twice as Long as Conventional Type
A motor's life is determined by its bearing. We adopted high-performance bearing grease to lubricate this important component. As a result, the bearings of the World K Series motors last twice as long as conventional bearings.
[Excluding 1 W (1/750 HP) and 3 W (1/250 HP) types.]
