EASA Senior Technical Support Specialist
Vertical motors differ from horizontal motors in numerous ways, yet some view them as “just a horizontal motor turned on end.” The obvious differences are the (usually) thrust bearings, with arrangements varying from single- to three-thrust bearings with different orientations suited for specific load, rpm and applications.
Less obvious differences are in the ventilation arrangements, shaft stiffness, degrees of protection and runout tolerances. This session will include:
- Bearing systems: Single, double or more?, Thrust direction, Angle of contact and rpm, Spherical thrust bearings, hydrodynamic
- Ventilation and cooling
- Operating environment, and enclosures: Enclosures (degrees of protection), ODP, TEFC, WPI, WPII (IP equivalents)
- Oil types and quantity: Bearing load and operating temperature, Consideration of speed, Sizing and adding cooling tubes
- Runout tolerances and repair methods: Upper bearing housing, Bearing carrier and shaft, Bottom bracket flange, Best practice methods for re-machining
This recording will benefit the service center owner, supervisor, technicians, sales personnel and customer.
