The fundamental mode of operation for gearing and its transmission of mechanical power remains unchanged — as has that for the electric motors with which they pair. But innovative variations have become increasingly common and include more custom gearing, compact designs, and better gearboxes and servogear sets (including helical gearing) for efficiency. Gearing and gearmotors […]
Above NEMA NXR 7100 motors offer power-dense design
ABB’s Above NEMA (ANEMA) NXR 7100 motors offer more horsepower per pound than conventional TEFC (totally enclosed fan cooled) motors, but with a smaller frame size in some power ratings. This helps save space, up to 8 in. in overall length in some cases, which enables more compact installations for industrial applications. The NXR 7100 […]
FAULHABER contributes to supply of medical care
The corona pandemic has meant an increase in demand for medical equipment, in particular ventilation and laboratory technology. With its drive systems, FAULHABER makes an important contribution in ensuring the reliable operation of equipment used in these now vital applications and is doing its utmost to safeguard supply. At the same time, the health of […]
Trends 2020: Motors get more connected — and more efficient
2020 is seeing new trends in the application of stepper motors as well as permanent-magnet synchronous motors (PMSMs), brushless motors, and direct-drive motors including torque motors. Perhaps one of the most dramatic trends is increased use of PMSMs or synchronous ac motors. They began seeing more use in the early 2000s, and now such motors […]
Motion-control systems help automate COVID-19 testing
Automated biochemical analyzers vastly accelerate the testing of patient samples in laboratories, which has become critical now that the COVID-19 pandemic has spread across the globe. Advanced automation with motor-based motion systems will help in the fight to hasten diagnosis. Just consider the cobas 6800 and 8800 machines from Roche that automate testing of nasopharyngeal […]
What are current and future MEPS for electric motors?
Minimum efficiency performance standards, or MEPS, specify the required efficiency levels for electric motors used in residential, commercial, and industrial applications. The goals of implementing MEPS are to increase energy efficiency, promote energy savings, and reduce operating costs for electric motors. And although work is being done to harmonize electric motor efficiency classifications, MEPS vary […]
What are international efficiency (IE) standards for motors and gearmotors?
According to the U.S. Department of Energy (DOE), electric motors are responsible for half the energy use in the U.S. manufacturing sector, and the International Energy Agency (IEA) estimates that electric motor-driven system account for more than 40 percent of global electricity consumption. To promote energy savings, increase efficiency, and reduce operating costs for manufacturing […]
Allied Motion to show KinetiMax outer-rotor brushless motor at Hannover Messe 2020
Allied Motion Technologies will present its latest innovations in motion technology at Hannover Messe 2020, in Hannover, Germany, April 20 – 24, in Hall 4, Stand E10. Among the products on exhibit, the company will feature its KinetiMax High Power Density (HPD) motors, an outer-rotor brushless motor designed for high-torque, low-cogging applications like robotics, AGVs, […]
Direct-drive linear motor features integrated encoder, temperature sensor
The new patented SDLM-019-070-01-01 direct-drive linear motor with integrated position and temperature sensors is the latest addition to the series of zero backlash, zero cogging, high acceleration, high speed, high resolution, long life motors from Moticont. Also known as an electric cylinder, this compact direct-drive linear motor is just 0.75 in. (19.1 mm) in diameter […]
What function do thermistors and KTY sensors serve in motors and gearmotors?
One of the most important operating parameters of motor and gearmotor operation is the temperature of the motor windings. Motor heating is caused by mechanical, electrical, and copper losses, as well as heat transferred to the motor from external sources, including the ambient temperature and surrounding equipment. If the temperature of the motor windings surpasses the […]
