How to mitigate heating in a handheld surgical tool

Here are two main sources of power losses, and hence heating, when it comes to handheld surgical tool motors. Urs Kafader, Maxon Motor Motors operated at the rated torque limit can get very hot. In continuous operation, the winding can reach 155 °C, resulting in a housing temperature of some 120 °C. No surgeon would

Sepac touts spring-engaged tooth brakes for medical applications

Sepac is touting its SETB electromagnetic spring-engaged tooth brake – designed to deliver reliable, consistent operation within medical applications. The power-off brake offers large bore sizes, low backlash, high torque-to-size ratio, a high number of index positions, positive engagement and a reliable coil with custom voltages available. Many of the features are not commercially available elsewhere

Maxon Motor touts sterilizable drive system

Maxon Motor has introduced what it says is the first sterilizable steam sterilizable encoder – the ENX Easy. The ENX Easy is a sterilizable encoder for use with Maxon’s brushless DC motors. Maxon officials say the ENX Easy opens new possibilities in medical technology. The ENX Easy’s compact and robust design is especially ideal for power tools, according to

Comparing spur versus planetary gearheads

Maxon Precision Motors Inc. The two most common and readily available gearhead designs are the spur and planetary versions. Each has benefits and drawbacks depending on the particular application. Spur gearheads are designed in such a way that two gears (a single stage) work together to increase the torque potential of the driving motor. Each

What are the pros and cons of dc brush and brushless motors?

Micromo, a division of Faulhaber One advantage of dc motors is the linear relationship that allows for predictable operation. For instance under cold conditions, the torque constant KM is the approximate motor torque production per ampere of current (In metric units: mNm/A). This is also true under warm conditions, but the thermodynamic effects on the torque constant and motor performance
