Maxon, a manufacturer of small, high-quality DC brush and brushless motors, announced key product developments for medical technology applications including the EC 9.2 flat motor and the KD 32 planetary gearhead. The company has also released a high density 200 W power pack in the RE 50 and a compact speed controller for brushless DC motors with Hall sensors with its DEC Module 24/2.
The EC 9.2 flat motor offers a high nominal torque of 0.83 mNm and a stall torque of 1.29 mNm. Its outer diameter of 10 mm includes a cover that protects against contact and can be used as a mounting aid during installation. The EC 9.2 is equipped with an 8-pole neodymium permanent magnet and preloaded ball bearings. The motor can be utilized for medical technology applications where space limitations may be a concern. Other features include high nominal torque and lifespan-optimized bearings. It is available with or without Hall sensors.
The new Koaxdrive KD 32 combines the best of worm and planetary gear technologies with a patent-protected design that has enabled Maxon to substantially reduce the noise in the first gear stage where the greatest peripheral speeds occur. This planetary gearhead measures 32 mm in diameter and can be assembled with various Maxon motors. These low-noise combinations can be used for hand tools and instruments that are primarily used on or near patients in the medical technology sector.
The RE 50 is an extremely dense power pack which results in detent-free running and minimized mass inertia. The combination of a two-pole neodymium permanent magnet with the patented Maxon winding technology results in high torque and remarkable acceleration. The drive can be used in battery-powered applications such as electric vehicles, transport and logistics equipment, mobile systems and robotics. A dust and water protected RE 50 will soon be available with an optional brake.
The DEC Module 24/2 is a wireless, plug-in module that can be integrated into most applications. A wide voltage range of 8-24 VDC and a continuous output of 2A allows flexible multifunctional operation at a high efficiency factor.
