Both EC Family motors are part of assemblies that include a planetary gearbox, […]
New flat brushless dc motor features integrated encoder
The new DF45 brushless dc motors from Nanotec are now available with an integrated encoder. The new flat motors have a diameter of only 45 mm and, owing to their extremely compact design, are suitable for applications that require precise positioning in confined spaces. The 2-channel encoder has a resolution of 1,024 CPR and provides […]
AMETEK Haydon Kerk Pittman introduces new 57-mm size in IDEA Motor series
AMETEK Haydon Kerk Pittman (HKP), a business unit of AMETEK, has released a new size in its IDEA Motor series of brushless dc motors: 57 mm. This EC057B joins the 42-mm EC042B product introduced in 2019 and enhances a line of motors with integrated, programmable drives. The IDEA Motor combines a precision brushless servo motor […]
Which types of DC motors can be used as servo motors? (And a refresher on DC motor technologies)
Servo motors are used in applications where precise control of position, speed, or torque is required. But many different types of motors can be considered servo motors — the defining feature of a servo motor is that it incorporates or reads feedback in a closed-loop system. In fact, although many servo applications use synchronous AC motors, […]
Successful lab experiments start with the right pipette motor
For medical lab applications, motor selection is integral to an electronic pipette’s accuracy and precision. Valentin Raschke Application Engineer Portescap Laboratory automation has always been a great fit for linear motion. Within certain laboratory devices, precision is required for moving samples into position, adding reagents, and withdrawing samples. Advancements in the linear force and speed […]
What are eddy currents and how do they affect motor performance?
One of the electromagnetic principles that governs the operation of an electric motor is Faraday’s law, which states that when the magnetic environment of a coil of wire is changed — whether by moving the magnet and coil relative to each other or by changing the magnetic field — a voltage, or electromotive force (EMF), will […]
