By Keith Halbert, PhD • Portescap || Device makers and surgeons have for decades relied on sterilizable brushless direct current (BLDC) motors to meet the torque, speed, and reliability requirements of surgical handtools. Now surgical robotics are leveraging these same capabilities. Today’s surgical robotics and robotically-assisted surgical devices often require BLDC motors to meet demanding […]

New outer-rotor brushless motor features high power density
Allied Motion Technologies has released the new KinetiMax High Power Density (HPD) motor series. The outer-rotor brushless motor is designed for high-torque, low-cogging applications like robotics, AGVs, and handheld power tools. An efficiency rating of over 85% coupled with a high power-to-weight ratio makes it an ideal motor for any application where weight and battery […]
Pedal electric cycles (pedelecs) employ FAULHABER electric motors
In many parts of the world, bicycles are central to the culture — both for recreation and practical transportation for everyday tasks such as shopping or commuting to and from work. Efforts to reduce CO2 emissions, concerns about climate change, and rising fossil-fuel costs in many areas (along with congested roadways) have only spurred more […]

When to use gears to change the inertia ratio of a motor-driven system
In any system where a motor drives a load to achieve precise positioning, velocity, or torque, the ratio of the load inertia to the motor inertia plays a significant role in determining the motor’s ability to effectively and efficiently control the load, especially during acceleration and deceleration portions of the motion profile. In this context, the […]
