Although new distributed servo drive systems promise incredible performance, engineers should consider cabling, form factor, and safety integration before standardizing on a platform. Servomotors with integrated drives were groundbreaking technology when they hit the market, but their full potential has rarely been reached. These servomotors are supposed to reduce footprint and commissioning time while increasing […]

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 […]
Motion Trends: New motor breeds are smart, connected, and compact
This year’s survey of trends in electric motors for motion control and automation revealed several trends and emerging developments in the use of synchronous ac motors; stepper motors, especially in closed-loop offerings; brushless motors of various types; and a smattering of specialty direct-drive offerings just making inroads. Proliferation of synchronous ac motors With construction and […]
New servo motor series from Kollmorgen
The new VLM servo motor series from Kollmorgen aims to fill the gap between stepper and high-performance servo motors. The new VLM series synchronous servo motors offer OEMs, machine builders and end-users, an excellent price-performance proposition in the torque range of 0.5 to 4.5 Nm continuous and 16 Nm peak, with speeds of up to […]
New 200-W high-torque brushless servo motor from maxon
The new EC-i 52XL 200-W brushless servo motor from maxon features a flux collector rotor which provides outstanding torque performance compared to the existing EC-i 52 180-W high torque motor. Especially on the industrial automation front, when space is limited but high torque and dynamics are required, the maxon EC-i 52XL motor with its extended […]
Integrated servo motor offers design benefits for mobile robotic applications
Applied Motion Products’ new series of integrated servo motors combine a high torque density, low inertia servo motor with an on-board drive and controller to save on space, wiring, and cost over conventional servo systems with separate motor and drive components. The MDX Integrated Servo Motors provide greater design modularity and simplicity for a wide […]
When do tubular linear motors outperform traditional iron core and ironless designs?
In a recent post, we looked at traditional iron core and ironless linear motors, both of which have a flat-type construction. But another type of linear motor, often referred to as a “tubular linear motor,” is also gaining traction in industrial applications. This is especially true in the packaging and medical industries, where tubular linear motors […]
New servo motor from JVL features built-in controller, nano-PLC
JVL’s newest high-capacity MAC motors with a rating of 3,000 W are complete servo systems including a high-dynamic ac servo motor, hall-sensors, encoder, power supply, driver and positioning controller and Nano-PLC, as well as facilities for incorporating various control modules such as Bluetooth, WLAN, ZigBee, EtherCAT, EtherNet/IP, CANopen, DeviceNet, Profibus, Profinet, Nano PLC, RS232/RS485/USB, and […]
