2015年11月12日 · Using soft starters and adjustable frequency drives reduce in-rush currents and limit torque—protecting valuable equipment and extending the motor's life by reducing motor heating caused by frequent starts and stops.

Soft starters are a type of motor control device that provides slow ramp-up (soft start-up) of the motor to help limit (moderate) mechanical shock and electrical peak demand. While a VFD can also control the specific speed of the motor, a soft starter can only control the acceleration and deceleration of a motor.

(DOL) start. When these motors are used together with a softstarter it is possible to reduce the starting current further when compared to motors with low starting torque. The number of poles also affects the technical data. A motor with two poles often has a lower starting torque than mo-tors with four or more poles.

Franklin Electric's soft starters provide an across-the-line start for emergency situations and offer adjustable current limits, start/stop voltages, and start/stop times. Our soft starters also require no fuses to help ensure you save time and money.

2015年2月1日 · Electronic starting and stopping of the pump motor is cost-effective and reduces surges or hammering problems. Here, Stuart Greenwood, product marketing manager for industrial control and automation at Eaton, explains why soft starters are becoming the control of choice for centrifugal pumping systems.

Soft starters can offer benefits for almost all motor starting applications. Typical advantages are highlighted in the table below. Table 1-1 Typical soft start applications Pumps Minimised hydraulic shock in pipelines during start and stop. Reduced starting current. Minimised mechanical stress …

Soft starters enhance start-up performance in various pump applications. They allow for effective management of the starting sequence, ensuring that pumps reach operational speed without the issues commonly associated with conventional start methods.

Find out how the soft start feature of the SQ/SQE brings an improved alternative to conventional 4” submersible pumps, offering quicker installation and increased pump reliability.

Multi-tap control power transformer with integrated secondary protection accommodates common motor voltages. No fuses required! Tru-power™ sensing protects the IPS-RV from dry-run, dead head, runout, and jammed impellers - keeping you online and …

SAF’s reduced voltage starters are designed for the unique challenges of pump applications of today’s clean water and wastewater pump applications.
