Solcon DriveStart

Posted by Advanced Controls & Distribution on Jul 18, 2018 2:04:40 PM

Soft starters are essential pieces of equipment for motor control that are cost-effective and time-savers. Most are used for fan and pump controls, but some applications can be unique to a particular problem.  

Solcon’s DriveStart is an IGBT-based medium voltage soft starter designed for applications that have a higher starting torque requirement and need a low starting current. The soft starter is able to bring down costs related to operations thanks to its robust design. When compared to a medium voltage VFD, the starter is much more economical and provides the same number of features.

Solcon iStart Overview

Posted by Advanced Controls & Distribution on Jul 13, 2018 11:22:49 AM

As cost-effective and time-saving devices, soft starters are essential pieces of equipment for motor control. Most are used in plants with older motors and fan or pump controls, but some applications can be unique to a specific problem.  

Dubbed Solcon’s most advanced soft starter, the iStart is an advanced low voltage soft starter rated at 17–1100 Amps, 208–690 Volts. It is designed to provide optimal performance during motor starts and stops so that top-tier performance can be guaranteed for all connected appliances.

Protection and Reliability in Motor Control: Soft Starters

Posted by Michelle Szemanski on Aug 31, 2016 8:42:15 AM

After a month without significant downtime or hitches, all seems right in the world, or at least your facility – until the energy bill comes in thousands of dollars above the norm.

Many manufacturers budget for unforeseen costs, but the penalty from a utility company for demanding too much power from the grid during peak hours can be incredibly harsh on the bottom line. When motors start malfunctioning the next month from mechanical stress or product starts getting damaged from rough movement through the conveyor line, you may need a soft starter.

Choosing Encoders for Harsh Environments

Posted by Alan Kuffner on Jul 29, 2016 8:21:43 AM

Optical encoders are useful in many industrial processes, from angle detection to the positioning of precision components. In most applications, standard encoders are suited well enough to do their job effectively. But in certain industries and environments, standard encoders have a rough time performing well and resisting failure. This failure can be caused by particulates, chemicals, excessive loads, and immersion in liquids.

Motor Control Centers – Yesterday and Today

Posted by Mark McCracken on Jan 25, 2016 12:14:06 PM

What do stadiums and steel mills have in common, other than Pittsburgh pride?

Both traditionally use Motor Control Centers (MCC), an automation technology that has deep roots in many manufacturing industries.

MCCs are an assembly of one or more enclosed sections having a common horizontal main power bus and factory assembled motor control units or buckets which are connected to a vertical bus. Historically motor control centers were an assembly of numerous motor starters or feeder breakers used to control individual motors.  Today they can incorporate variable frequency drives, soft starters, solid state/digital control devices, PLCs, HMIs and contain network communication protocols such as profibus, profinet or ethernet.

What else can a servo motor do?

In Servo Motors: An In-Depth Introduction, Part 1, we reviewed how servo motor construction and operating characteristics create this technology's advantages. But there's more to understanding how servo motors can play an important role in automation solutions. Shaft sensors and holding brakes provide 4 different kinds of feedback and can extend the life of the equipment for maximum efficiency.

Here's how:

Soft Starters – Applications and Benefits

Posted by Mark McCracken on Nov 24, 2015 9:12:35 AM

Old motor controls used an across-the-line starters or some type of Wye or Delta configuration to start and stop electric motors.  Across-the-line starters can produce in-rush currents up to 7 times the normal operating motor current and 3 times the starting torque when compared to motor operating torque.

A soft starter electronically controls the voltage applied to the motor via SCR’s during starting and stopping, which in turn controls the speed and current levels.

Servo Motors: An In-Depth Introduction, Part 1

Posted by Dave Gazda on Oct 30, 2015 1:40:42 PM

What is a servo motor, and what are they used for?

A servo drive system breaks down into two main components: the servo motor and a servo drive. The servo drive converts electrical power from the connected line supply in a controlled manner into power for the motor. The servo drive consists of power electronics and control electronics for regulation, set point generation, and component monitoring.

The servo motor converts the electrical power into movement. It consists of torque generating components, the sensor for angle and feedback and, in some cases, a holding brake to maintain position at zero current. Generally, the operation of servo motors is characterized by frequent changes in speed and torque, operation at standstill to hold positions, and short-term operation with high overloads.

To understand the advantages of a servo motor, let's consider the inner workings: construction, operating characteristics, sensors, and brakes.
