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.

SpletA contactor is an electrically-controlled switch used for switching an electrical power circuit. [1] A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. Unlike general-purpose relays, contactors are designed to be ... Splet09. feb. 2010 · Normally, the contactor holding should close when there is power. Physical Barriers If the reason why the sealing circuit does not close is because of any physical barrier that isn’t a safety feature such as dirt or dust, then simply remove it. You want to make sure that you unplug it or turn off the breaker to keep safe.
