Features
- They feature a TEFC (totally enclosed fan-cooled) enclosure, preventing the free exchange of air between the interiors & the exteriors. It cools the motor windings with the help of an exterior fan when overheated.
- They incorporate an oversized ball bearing that exhibits low friction loss, works well on high-speed operations and is compatible with a wide range of temperatures.
- Models such as, 254TTFCD6037, feature a C-face mounting design that allows for direct coupling with the equipment and the motor is cantilevered with the help of a heavy-duty flange.
Standards and Approvals
- UL
- CSA
- CE
Frequently Asked Questions
How to maintain the motor?
To keep the motor running smoothly, use permanently lubricated sealed bearings to work on overloads and reduce friction.
What is the IP55 rating?
IP55 rating protects against dust and water jets from any direction.
What is Class F insulation?
Motors with class F insulation withstand a maximum temperature rating of 155 degrees C. It can be enhanced with adhesives, silicone and alkyd-resin varnish of higher thermal endurance to resist damage.
