What kind of starter do I need for slipring motor?
What kind of starter do I need for slipring motor?
The MV enclosure is normally included with the starter, but for higher ratings, it may be supplied in a separate control panel. The EPM rotor starter is normally used to control the starting of a slipring motor, and the starting current is generally limited to a maximum of 250% FLC.
When to use EPM electrolytic starter for slipring Motors?
It will supply the power necessary to drive the motor by resistance variation. EPM electrolytic starter can be used to start slipring motors from 500 kW to 20,000 kW. It will supply the power necessary to drive the motor by resistance variation.
How long is the run up time for an electrolytic starter?
Starting times are adjustable from 10 to 150 seconds. Control and interlocking: Limit switches are incorporated to control the geared motor, and to power the shorting contactor which shorts out the residual resistance at the end of the run up time.
What is the operating principle of EPM rotor starter?
Operating principle. The EPM rotor starter is normally used to control the starting of a slipring motor, and the starting current is generally limited to a maximum of 250% FLC. Optimal starting torque for each application is normally selected by the choice of the initial value of resistance.

Can a block mounted starter be used as a starter?
When using a block-mounted starter, it wise to use the special, knurled starter bolts to correctly position the starter. Using incorrect starter bolts is a leading cause of noisy starters. Installation procedure of the bolts is also important.
How much clearance do you need for a starter?
We can’t talk about starter mounting, and not mention shims. Sometimes, you will need to use a shim to give the proper clearance between the starter drive gear and the flywheel/flexplate ring gear. A rule of thumb is that there should be .030-inch of clearance between the gears when the starter is engaged.
