In 2011, the EU implemented minimum efficiency performance standards (MEPS) for electric motors used in residential, commercial, and industrial applications with Commission Regulation (EC) 640/2009, which was implemented in three stages through 2017, and its amendment Regulation (EU) 4/2014. In October 2019, Regulation (EC) 640/2009 was replaced with Commission Regulation (EU) 2019/1781, which outlines updated efficiency […]

Piezo motor for nano-metrology applications with nanometer precision
PI’s line of lens positioners, designed to scan and position objectives with sub-nanometer resolution at high bandwidth, is expanding with a new generation of piezo Z-focus stages – the P-725 PIFOC piezo flexure stage product family. Available in 3 travel ranges of 100, 400, and 800µm, high performance fast focusing with nanometer precision is achieved […]
New line of brushless dc flat motors from Orbex
The Orbex Group has introduced a new line of flat brushless dc motors. These compact motors, available with or without encoders, are useful for applications that require high torque density and have space limitations — including robotics, packaging, security, medical and more. These high-performance motors feature a range of sizes, voltages and speeds, giving the […]
Customized and reliable stepper motors address HVAC damper application extremes
In any HVAC (heating, ventilation, and air conditioning) system, dampers are used to regulate airflow inside the ducts. In some systems, manual dampers allow personnel to turn a handle on the outside of a duct. But if you have to regulate airflow on a constant basis, you’ll need automatic dampers with electric or pneumatic motors […]
New compact servo motor features integrated positioning controller
maxon’s new IDX compact integrated servo gearmotor + drive combines a powerful, brushless EC-i motor and an EPOS4 positioning controller with field-oriented control (FOC), which can be complemented with a maxon planetary gearhead when required. This integrated motor stands out for its high torque density, high efficiency, maintenance-free components, and a high-quality industrial housing providing […]
Low-profile kit-style limited angle torque motor
The TMR-075-16-001-2 limited angle torque motor utilizes a toroidally wound, stationary coil assembly with a two-pole permanent magnet rotor to generate torque. The rare earth permanent magnet rotor always has an even number of poles, with two to six poles. The maximum angular excursion with a two-pole rotor is 180º, but the torque will drop […]
SDP/SI adds integrated motors to simplify motion system design
Stock Drive Products/Sterling Instrument (SDP/SI) has launched a series of Integrated Motors to simplify motion system design. Replacing multiple components with a compact all-in-one motor and electronics package, Integrated Motors simplify motion system design while providing many advantages. “Doing speed, position and torque closed-loop control with separate brushless motor and driver/controller technologies can be challenging,” […]
How to calculate continuous and peak torque values for servo applications
One of the most important tools for sizing a servo motor is the motor’s torque-speed curve, which shows the combinations of torque and speed that the motor can produce in two operating zones — continuous operation and peak, or intermittent, operation. To prevent thermal overload of the motor — and the drive — it’s important to […]
What is a direct drive in the context of motion applications?
In the most common motor-driven systems, the motor is coupled to the load being moved by a mechanical transmission element — a belt, chain, rack and pinion, ball or lead screw, or even simply a gearbox. But some linear and rotary motion systems do away with mechanical transmission elements and couple the load directly to […]
