QuickSilver Controls, Inc. has announced the availability of the SilverMax line of hybrid servo motors. Hybrid servos provide superior continuous torque at low speeds transitioning to nearly constant power curves up to 4,000 rpm. They are well suited to direct drive of lead screws and belt drives, typically eliminating the need for gear heads. The […]
New mechanically compatible absolute shafted angle encoders
HEIDENHAIN announces the start of series production of their ROC 2000 and ROC 7000, a new family of Absolute Solid Shafted Angle Encoders. Using the same mechanical connections and footprint as their incremental cousins (the ROD series), and the same scanning principles as their hollow shafted siblings (the RCN series), the ROC series is the […]

PI’s newest compact rotary stage is 32 mm wide x 7 mm high
PI (Physik Instrumente) recently added a new piezo inertia drive rotary stage to its existing Q-Motion product line of compact linear and rotary systems – the Q-632. This compact micropositioning drive is only 32 mm wide, 7 mm high, and has a 30 mm turntable diameter with 360° rotation range. The Q-632 delivers precision rotation […]
Angle encoders with mechanical fault exclusion for functional safety
HEIDENHAIN Corporation has announced the first and only angle encoders on the market to have a Fault Exclusion for loosening of the mechanical connection. This is a primary prerequisite for encoders meeting Functional Safety standards required for any machines shipped to Europe. Since safety is always a concern for any machine user, now peace of […]
Drive/motor combo cuts extruder energy usage by 9%
Recently, Emerson Industrial Automation was able to help Stål & Plast, a Danish extrusion specialist, improve its production processes by replacing three worn-out dc electric motors with Dyneo PM motors and a Unidrive M variable speed drive at the company’s extruder plant. Stål & Plast A/S of Denmark manufactures bench tray systems used in greenhouses […]
Direct-drive, hollow-shaft motors from Empire Magnetics
Empire Magnetics offers hollow-shafted motors for industrial processes, such as manufacturing fiber optic cable and designing radar antennas, robots, and high-speed laser scanner systems. Direct-drive hollow-shaft motors increase speed and acceleration, while providing better accuracy and faster response times when compared to motor driven mechanical arrangements. Mechanical drive arrangements add inertia to a system, resulting […]
Rotary encoders from HEIDENHAIN meet new standards for explosive environments
HEIDENHAIN’s ATEX series of encoders for potentially explosive atmospheres meet the new standards required today for motion control applications. These HEIDENHAIN ExN and ROx 400 rotary encoders feature a sturdy design with increased wall thickness, smaller cable diameter, and variations for multiple zones and atmosphere classifications. Many industries, such as oil and gas, printing, and […]
New 2-phase stepper motors with electromagnetic brakes from Oriental Motor
Oriental Motor’s new 1.8° and 0.9° PKP Series 2-phase stepper motors are available with built-in power-off activated preassembled electromagnetic brakes. When power is accidentally cut off due to unexpected events, such as a blackout, the electromagnetic brake holds the load in position to prevent it from moving. When the motor is at standstill, it can be […]
