The hybrid servomotor: stepping up to closed loop
by Don Labriola P.E., President, QuickSilver Controls, Inc The use of hybrid servos grows as their control techniques are understood, and the costs of sufficient processing power shrink. Sophisticated control techniques have produced the hybrid servomotor system from the motor style commonly called a hybrid stepper motor when powered by an open-loop step driver. The […]
New for mobile motor designs: Battery-powered speed controllers
KB Electronics now sells two battery-powered speed controllers … dc/dc low-voltage motor speed controls. The KBBW Series of pulse-width-modulated (PWM) dc/dc motor speed controls respond dynamically to load variations. PWM produces an almost pure dc current to the motor for low noise and long brush life. Pulse-by-pulse current limit provides short circuit protection and prevents control […]
New line of stepper motors from Nook Industries
Nook Industries has introduced a line of new stepper motors designed to provide a total, single source for linear motion solutions. The new line can power ball screws, actuators, jacks and linear modules with a variety of load, speed and power supply options, in two basic configurations: Stepper motors and integrated stepper motors. A wide […]
Bonfiglioli IE3 motors are more efficient than others
Bonfiglioli now sells BX/MX motors that are more efficient than other options. The ongoing worldwide process to improve electric motor efficiency is top priority for the company. According to the international standard IEC 60034-30, the motors meet IE3 efficiency-class standards. The X of the new BX/MX motors stands for “eXcellence” in efficiency. That’s because the IE3 is the top […]
Baldor Electric launches new website with powerful search and download capabilities
Baldor Electric Company recently launched its new Baldor.com website, a robust destination site for North American industrial motor and mechanical users. “The new site not only showcases our broad product offering and our strong product brands, but it does so in a much easier and faster way than ever before,” said Tracy Long, Vice President […]
Revamped servomotors from B&R more powerful
Revamped 8LS series servomotors from B&R are now more powerful than ever. A more compact housing, optimized design and additional sizes are other improvements. Size 2 and 3 servomotors with the same technical capabilities are now much more compact for maximum compatibility and higher power density. Size 5 and 7 motors come in additional lengths for better dynamics and torque. Inductive […]
Step motors take a step in the right direction
Because stepping motors are relatively inexpensive and easy to control, they’re often the first option to consider in machine designs. Low-cost solutions have had performance limitations, but new control technology substantially enhances stepping motors capability. Stepping motors have progressed over the years from the early days of the world’s first digital motor into a broad […]
Gearmotors: More integration, more applications
Gearmotors have been around since at least the early 20th century, so it’s a fairly well-established technology. (A basic gearmotor is a motor designed with an integrated gear reducer.) However, that doesn’t mean that gearmotors have not been improved upon over the years. Nor does it mean that they’re an outdated technology. In fact, there […]
New trends in electric motors: Efficiency, power density, torque
If there’s one trend that’s prevalent in motors of all kinds, it’s the theme of increasing performance, more specifically a trio of highers: higher efficiency, higher power density and higher torque density. These are incremental improvements in motor performance that are at least partly driven by the Department of Energy (DOE) energy efficiency requirements, said […]
