The Allen-Bradley SMC-50 Smart Motor Controller from Rockwell Automation is the company’s latest generation of solid-state motor controllers.

Featuring a newly designed three-phase, fully solid-state, silicon-controlled rectifier (SCR) power structure, the new SMC-50 addresses the motor control needs of OEMs and end users seeking a more economical alternative to drives and more advanced control than across-the-line starters.

Designed for customer flexibility, the SMC-50 combines advanced monitoring and protection features, multiple start and stop options and expandable control inputs and outputs. These features to help users to increase efficiency, reduce downtime and improve control.

The SMC-50 Smart Motor Controller’s design improves voltage output to maximise efficiency of motor starts and stops. For application scalability, it features nine standard starting modes, six stopping modes and several slow-speed functions. In traditional starting mode, for example, if the SMC-50 senses that the motor has reached full speed before completing the selected ramp time, it will automatically switch to providing full voltage to the motor. The patented linear acceleration starting mode offers the lowest starting current profile per start, consistent acceleration time and enhanced control over both torque and speed. Regardless of the starting mode chosen, the SMC-50 stores the actual motor start time and peak current value to assist in set-up and process optimisation.

Depending on the application, controlling voltage during motor stopping is equally critical to controlling voltage during motor starts. For example, the SMC-50 Smart Motor Controller using Smart Motor Braking engineered with automatic zero speed shut-off, quickly stops a motor without the need for additional hardware or feedback devices.

The SMC-50 Smart Motor Controller’s combination of standard and advanced features combined with user programming options, scalable I/O options, and network integration capabilities provide the excellent motor performance and energy management.
