When we rebuild electric motors and help customers solve application problems, there are two unique accessories that are worth reviewing. Because eddy-current couplings and fluid couplings are uncommon, the institutional knowledge about them is being lost. This webinar recording is intended to preserve the knowledge of how they work as well as their unique repair requirements.
The eddy-current coupling or clutch is old-school technology, but their robust design is appreciated by many industries.
- How an eddy-current coupling works
- Drum and spider design features
- Pilot bearing and internal alignment “shaft deflection”
- Lubrication features
- Cooling requirements
Fluid couplings offer a reliable method for an electric motor to accelerate normally while the driven high-inertia load accelerates more slowly. These offer a good alternative to special Design C or D motors. As simple as they appear, the fluid coupling is very expensive and offers another revenue stream for those able to work on them.
- How a fluid coupling / clutch works
- Adjusting acceleration time and torque transmission
- Repair tips and essentials
- Bearing replacement
- Sealing the halves
This webinar explains how each of these devices work, with repair tips and application information for each.
