Portescap’s newest surgical motor for large-bone orthopedic powered hand tools is a size 12 (31.5 mm diameter) mini motor available in 9.6-V, 12-V and 14.4-V. With cannulated and non-cannulated options, these motors can deliver peak torques of up to 1,720 mNm in a compact envelope. These drives are suitable for various applications such as orthopedic […]
AutomationDirect adds more Koyo incremental and absolute encoders
AutomationDirect has expanded its Koyo encoder product line to include additional incremental encoder output options and higher resolutions for absolute encoders. The TRD-S Series of 6-mm solid shaft and TRD-SH Series of 8-mm hollow shaft incremental encoders now have 5-12 Vdc open collector output versions in addition to the existing 12-24 Vdc open collector or […]
Q-link VFD from Franklin Control Systems features smartphone connectivity
Franklin Control Systems’ Q-link Variable Frequency Drive provides a unique user experience through intuitive smartphone operation. The drive was designed from the ground up for HVAC applications and users in that industry, with streamlined start-up, reporting, and support. The Q-link provides an array of inputs and outputs including damper control. The Q-link uses R3 filtering […]
What are digital signal processors (DSPs) for motion control?
Digital signal processors (or DSPs) are dedicated ICs that can be programmed to execute specific types of calculations or algorithms. They differ from standard microprocessors in that they are not designed to do much if any of the supervisory tasks that microprocessors typically handle. This is why they can execute algorithms much faster than microprocessors […]

Under the new partnership, HC Pacific will provide this state-of-the-art coupling solution to the domestic marketplace. This agreement, effective October 1, 2017, will expand HC […]
Remote connectivity among features of Mitsubishi Electric’s newest widescreen HMI
The latest human machine interface (HMI) from Mitsubishi Electric Automation, Inc. is the GT25 Wide HMI, an interface that monitors and controls machine components with a graphical touchscreen that connects to equipment such as PLCs, VFDs and servos. Information is displayed on high-resolution screens – 7-in. wide video graphics array (WVGA) or 10-in. wide extended […]
For hybrid servomotors, does pole count matter?
For a given rotor diameter, the number of magnetic poles on the rotor directly affects the torque available, the top speed available, and the power needed to hold a load. Higher pole counts lead to higher torque, lower top speed, and a higher motor quality factor, which is defined as Kq = T / √ […]
Hybrid servos vs. standard servos: How do they stack up?
A new type of integrated hybrid servo motor is finding use in direct-drive applications where it offers lower cost, smaller size, and higher efficiency than conventional servo motors. Donald Labriola P.E. QuickSilver Controls, Inc. No single motor type has advantages in every application. Direct-drive applications favor so-called hybrid servos while high-speed geared-down applications tend to […]
What is PC control for motion?
Motion controller architectures can be one of several types. Among the most common are stand-alone controllers and PC-based control. PC control for motion typically takes the form of so-called industrial PCs. These feature processors just like a typical PC but a lot of the other components are ruggedized and designed for operation in an industrial […]
MAXXDRIVE industrial gear units from NORD now in more sizes
NORD Drivesystems recently added two new sizes to the MAXXDRIVE line. The new 133,000 & 177,000 in-lb nominal torque units are a well-received addition to the now 11-member family, complementing the larger units and promising even greater flexibility to system designers. The entire MAXXDRIVE line is modular, and can be configured with a wide array […]
