GE offers a wide variety of electro-mechanical reduced voltage starting methods. These include the CR330 series part winding starters, the CR331 automated type and the CR333 series Wye-Delta magnetic starters. Users of squirrel cage motors face a variety of application issues that make some form of reduced current or reduced shock loading starters necessary especially with larger motors. GE's line of reduced voltage electro-mechanical starters will fulfil this need. Part windings and Wye-delta forms require specially wound motors that essentially employ a winding for starting and another for running. The starter performs the switching function to reconnect the motor winding. The autotransformer starter uses a 3 leg transformer to reduce the voltage during startintg and reconnects the motor to full voltage during running. Taps may be set to match the application.
