When engineers are looking to buy a motor, the question most often asked: Is AC or DC technology better? The answer isn’t that one is better than the other. Rather it is application and cost dependent. Here we will discuss the options and specifically the advantages and disadvantages of each. Furthermore, it is often a […]

Over the past 50 years, Dart Controls has always been about innovation. Staying ahead of the technology curve gives our customers an extra edge over their competition. One product we embraced early on is the brushless DC motor. Introduced in the 1960s, the brushless DC motor brought with it a number of benefits. Unlike AC […]
Reports of the death of DC motors and drives “have been greatly exaggerated” (to borrow from a well-known writer). For over 30 years, industry pundits have been predicting the demise of the DC motor/drive market, in favor of AC. Yet DC stubbornly clings to life. A DC drive is a direct-current motor speed control system. […]
Motor control makers are increasingly turning to protocols such as the Ethernet family to network the machines their products operate. According to IMS Research, the use of Ethernet in motor drives and motion controllers will “more than triple” by 2016. As this conversion progresses, the creation of networked manufacturing facilities also creates the possibility of […]
Baking, curing, heat-treating and drying ovens use conveyors to move product through the process quickly and efficiently. Dart Controls offers Digital DC Drives and Digital Accessories that provide several unique enhancements for these applications:
Only Dart Controls can offer Digital DC Motor Controls ideally suited for injection, treatment and batching pumps up to 2HP. Dart also offers more traditional drives with isolated signal follower inputs and integral Auto / Manual switch.
Brushless DC (BLDC) motors have the performance advantages of DC permanent magnet motors without the need for motor brush maintenance. BLDC motors have the additional advantages of very high base speed (20,000 RPM and higher), quiet operation and energy efficiency. In years past these advantages came with an initial investment premium. Today that premium over […]
