SMC-3, SMC Flex, and SMC-50 Smart Motor ControllersOverviewRockwell Automation offers a wide array of starting solutions that range from electromechanical to solid-state. Products that usethese methods include across-the-line starters, Smart Motor Controllers (SMC s), and variable frequency drives.SMC ControllersAllen-Bradley SMC controllers are micro-processor based soft starters that are designed to maximize the efficiency of motor startsand stops. SMC controllers are designed to operate 3-phase motors. They feature built-in overload protection and use six siliconcontrolled rectifiers (SCRs) (two per phase) to vary the conduction period and control the voltage (and thus, the torque) to themotor during starting, running, and stopping.Once the motor has been started and is up to speed, full input voltage is applied to the motor. At this point, units with internalbypass power structures bridge the SCRs with their integral bypass contacts, which are rated for AC1 current levels. Bridging theSCR minimizes heat and allows a smaller product for space-conscious applications. In solid-state power structures, the SCRs arealways in the circuit switching current. This allows increased robustness for harsher environments (such as shock-type loads) andmore aggressive duty cycles.Allen-Bradley SMCs are ideal for a wide range of applications. The product family consists of three major offerings.SMC-3Compact design provides true three-phase control, increased intelligence and unmatched performance. Motor and systemdiagnostics and an electronic overload with adjustable trip class reduce downtime and protect valuable assets.
