Baldor Soft-Starter Benefits

Power factor optimization eliminates motor over-fluxing and allows under-loaded or over-sized motors to operate more efficiently.

The Digital Soft-Start control features include microprocessor logic, NEMA Type 1 enclosure, and alphanumeric English language keypad display.

Benefits of Baldor Digital Soft-Start Control

• Reduced wear on mechanical gears, chains and sprockets, broken belts and jammed gearboxes.
• Lower inventory of mechanical parts and operating costs.
• Increased production rates by reducing machine maintenance downtime.
• Prolonged life of switchgear with lower inrush currents.
• Energy optimizing reduces motor energy losses when operating motor below maximum capacity.

How It Works

Baldors Digital Soft-Starter’s energy optimizing system works by reducing the current and iron losses of a motor not running at full load. The energy savings will depend on a number of factors including the efficiency of the motor and the load.

The optimizing feature is a purely electrical function which has the effect of ensuring that motor delivers the torque demanded at all times, but only drawing the precise amount of magnetizing current necessary to support the motor output. Without this feature, the motor would draw a constant magnetizing current based on the supply voltage regardless of load.

The reduction of current proportional to load results in a lower I2R losses giving rise to an improvement in motor efficiency that is both continuous and cumulative.

These soft starters will also save money by reducing the electrical and mechanical strain placed on applications – resulting in less ‘down time’ and maintenance cost on electrical circuits, gearboxes, belts and associated mechanical components.
