Ultra-efficient motors improving cordless consumer-appliance performance
25 trillion kilowatt hours of electricity are consumed globally per year — of which 53% is consumed by electric motors. So replacing traditional electric motors with ultra-high-efficiency electric motors in all sorts of industries could significantly reduce energy wasted to noise and heat — and increase the performance and cost effectiveness of motor-driven designs in […]
Koford Engineering introduces high-speed brushless, slotless hall sensor motor
Koford Engineering LLC has introduced a new brushless, slotless hall sensor motor featuring speeds to 81,408 rpm and 153 W of power in a 22mm diameter. It features ceramic hybrid bearings with machined Torlon retainers and ultra low loss laminations. The slotless construction is free of cog. The motor has a hardened and precision ground 440C shaft […]
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 […]
How to calculate required input power for a gearmotor
The first place to start when sizing a gearmotor is to determine the required output torque and speed. But once torque and speed are defined, you’ll also want to know the required input power for the motor — particularly if the gearmotor uses an AC induction motor, where the power rating (typically given in horsepower) […]
Swiss precision motors handle valuable Mars soil samples
Was there once life on Mars? This is the question that one of the most complex robotic systems ever built by humankind has set out to answer. Several of maxon’s electric drives are used for handling the soil samples — and to control the first Mars helicopter. The rover named Perseverance entered the atmosphere of […]
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 […]
What is field weakening and how does it affect servo motor performance?
Although servo systems can very precisely control motor speed, position, and torque, in some applications, the motor may not be able to reach the commanded velocity due to limits in the available bus (supply) voltage from the drive. But advanced servo drives offer a technique referred to as field weakening, which alters the motor’s torque-speed […]
BG series of Dunkermotoren now available with integrated PROFINET interface
Modern machines and devices use all available process data to optimize them and make them transparent. PROFINET as a communication standard is ideally suited for this. Dunkermotoren early on integrated PROFINET functionality, including the PROFIdrive profile with application classes 1 and 4, into motors as standard. This offers PROFINET users significant advantages in cabling, commissioning […]
New miniature linear voice coil motors from Moticont
The new LVCM-010-013-01 linear voice coil motor from Moticont is only 0.375 in. (9.5 mm) in diameter and the length at mid-stroke is just 0.81 in. (20.7 mm) long. However, this new miniature voice coil motor has a high force-to-size ratio with a continuous force of 1.0 oz (0.28 N), a peak force of 3.2 […]
