Although new distributed servo drive systems promise incredible performance, engineers should consider cabling, form factor, and safety integration before standardizing on a platform. Matt Prellwitz Drive Technology Application Specialist Beckhoff Automation Servomotors with integrated drives were groundbreaking technology when they hit the market, but their full potential has rarely been reached. These servomotors are supposed […]
Servo motor offers increased torque, speed and efficiency in compact footprint
Kollmorgen’s AKM2G synchronous servo motors are the next generation of its AKM motor product family, and provide increased capabilities for demanding applications. The higher torque density of the AKM2G allows OEMs to substantially increase machine performance without increasing motor size. Greater flexibility and wider speed range enables machines to run faster, move heavier loads, and […]
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 […]
What is disturbance rejection in motion control?
One of the key functions of a motion controller is to create the trajectories the motor follows in order to reach the target position (or velocity or torque). As the motor turns, the controller processes feedback from the encoder and compares the actual position of the motor with the desired position. If there are any […]
Compact step motors with high torque for space-limited applications
Applied Motion Products offers compact step motors in NEMA sizes 8, 11 and 14 for applications with limited space including medical devices, 3D printers, analytical and medical instruments, robotics and others. These lightweight and low-cost motors offer high torque up to 22 oz-in. at low speed. Even while sized smaller, the compact step motors operate […]

As part of a product partnership with Siemens, Dunkermotoren BG series motors are now also available in specific versions compatible with the new Siemens SIMATIC MICRO-DRIVE servo drive system. The series BG 45, BG 65(S), BG 75 and BG 95 are 24 to 48 V brushless dc motors with power ranges from 20 to 1,000 […]
New brushless motor with integral drive from Allied Motion
Allied Motion Technologies’ new EnduraMax 75i Series is a 75-mm diameter brushless dc motor with an all-digital integrated drive. The EnduraMax 75i is capable of controlling torque, speed, and position in a wide range of commercial and industrial applications including: AGV vehicle traction or steering, medical patient-handling equipment, rotary/linear actuators, pumps, mobile HVAC blowers, and […]
AC induction motor inertia: What’s the difference between WK2 and WR2?
In any motor-driven system, the difference between the motor inertia and the load inertia will affect the system’s performance — especially its ability to accelerate the load quickly and efficiently. While servo motors are the preferred choice for applications that specify a precise move profile, AC induction motors are often the better choice for applications […]
Electric cylinders with programmable integrated motors
Captive shaft electric cylinders are now available for Lexium MDrive (LMD) integrated motor products. Quiet, clean and compact, these LMD products integrate motor, controls, and electric cylinder to deliver linear motion. And, unlike pneumatics, there is no need for compressed air, eliminating maintenance and noise issues. Lexium MDrive products integrate 1.8° 2-phase stepper motors with […]
