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 […]
Portescap integrates driver into new mini brushless dc motor
Portescap’s new 22ECP miniature brushless dc motor includes an integrated driver to optimize motor performance and simplify installation. The new 22-mm diameter motor is just 35 mm in length and delivers 50 percent more continuous torque than comparable brushless slotless miniature motors, without compromising smoothness of operation or motor lifespan. The new motor is the […]

New brushless motor features high speed, high power
A new brushless, slotless motor from Koford Engineering LLC features high speeds to 104,297 rpm with 94% peak efficiency with 980 W of power in a 42-mm diameter. Available with either hall sensors or sensorless, it features custom ceramic hybrid bearings with machined Torlon retainers. The slotless construction is free of cogging and nickel-iron laminations […]
Compact external rotor motors with integrated encoder from Nanotec
The DFA68 and DFA90 series brushless dc motors from Nanotec are now available with integrated encoder. Their extremely compact design makes the new external rotor motors particularly suitable for applications that require precise positioning in confined spaces, such as AGV wheel drives, access control gates and door drives. Both motors are equipped with a 3-channel […]
How custom BLDC motors boost performance and lower costs
From packaging to communications, BLDC servomotors are gaining market share in a variety of industries — and for good reason. They deliver high torque and smooth rotation (with minimal torque ripple) and lend themselves well to cost-saving customization. By Ralph Adams • President | Orbex Group Design engineers typically rely on off-the-shelf brushless dc (BLDC) […]
Brush DC versus brushless DC motors in disposable tools
Disposable medical hand tools are seeing increased use due to their cost and hygiene benefits. Engineers who design these tools usually specify brush DC or brushless DC motors. Here we compare these two options. By Clémence Muron • Applications engineer | Portescap An early step of surgical power tool engineering is to determine whether the […]
