AC Relays are solid magnetic cores. AC relays are energized satisfactorily on dc with a slowed up response due to the shading coil. AC relays operate on about 9 volt-amperes with coils up to 115 volts. These AC relays are built-in silicon, germanium diodes or copper oxide rectifiers depending on the performance requirements.
AC Right Angle Gearmotors are geared with hardened steel worm and forged bronze gear. It is lubricated with precision-machined die cast aluminum lubrication. These motors are supplied with mounted junction box, capacitor and rear extension for brake.
AC synchronous generators are generally used as stand-by electric power supply for domestic purposes and also as isolated power supply in remote and hilly areas where grid supply is not available. It is coupled to a prime mover like internal combustion engine, or wind turbine for using as generator set. Brushes and slip-rings are used in the machine to tap out the power.
