Soft Starters
Because of their simplicity and reliability, they are among the most widely used motor control devices in the world. When used with three-phase motors, they provide extremely smooth acceleration and deliver controlled torque. Although a soft starter does not qualify as a motor control device, it regulates power input in a simple and elegant manner. When a belt drive or coupling is involved, using a mechanical soft starter may be one of the simplest ways to improve service life and reduce maintenance costs.
Regarding the design for torque control and optimized motor speed, soft starter models come with the flexibility needed for motor acceleration management and the preventive measures desired against sudden surge and electrical stress. Their use allows for voltage adjustments and inrush current limiting, acts that provide in the kinds of systems served by soft starters—largely pumps—with an efficiency and savviness that increase longevity and VRM (voltage risk management). In the kinds of pump application scenarios that lie at the low end of the pricing spectrum in our power utility world, one sees soft starters quite often.
