SpletThe magnetic field for a synchronous machine may be provided by using permanent magnets made of neodymium-boron-iron, samarium-cobalt, or ferrite on the rotor. In some motors, these magnets are mounted with adhesive on the surface of the rotor core such that the magnetic field is radially directed across the air gap. In other designs, the … SpletA magnetic starter has a contactor and an overload relay, which will open the control voltage to the starter coil if it detects an overload on a motor. Overload relays may rely on … SpletIn a magnetic motor starter, when the coil is ener- gized, a normally open (NO) set of contacts will close, and a set of normally closed (NC) contacts will open.
