Miki Pulley’s BXR-LE electric spring applied brakes are suitable for small and precise servo motor configurations. Their unique compact and lightweight design optimizes servo drive performance and efficiency. With accompanying voltage controller, the brake’s power consumption is stepped down to 7VDC after a split second of 24VDC for brake actuation. When compared to most other […]

How to kill your favorite variable frequency drive
Though not a complete list, following are some tried-and-true methods some have unintentionally used to destroy variable frequency drives (VFDs). Avoid the following situations to help your VFD live a long and fruitful life. By Paul Avery | Product Training Engineer at Yaskawa America • Drives and Motion Division You once loved your VFD. Shiny […]
How do pulse-duty servo drives and motors differ from continuous-duty versions?
Servo systems are applied in a wide range of applications, from intermittent operations that require high torque output for quick acceleration and deceleration — such as pick-and-place from a conveyor — to processes that call for nearly uninterrupted operation with constant speed and torque requirements — such as printing, roll feeding, and labeling. Given these dissimilar application requirements and […]
Selecting a servo drive: 9 things you need to know
Sizing a motor for a servo application requires evaluating the move profile and torque requirements to determine the mechanical demands of the system, such as maximum velocity and acceleration, RMS and peak torque values, and load-to-motor inertia match. Once the motor is chosen, the next step is to select a drive. On the surface, selecting […]
400-Volt servo motors — now with Yaskawa Sigma-7 performance
The Drives & Motion Division of Yaskawa America, Inc. announces the addition of a complete line of 400 Volt servo motors and amplifiers to its flagship series of Sigma-7 servo systems, extending the performance advantages of Sigma-7 products to all types of industrial users. The new 400 Volt offering includes a completely new amplifier design […]
What are servo drive loops?
Servo drives, also called amplifiers in the motion-control industry, take a command signal for position, velocity, or current and adjust the voltage and current applied to the servomotor based on closed-loop feedback. In fact, a servo drive is just one element of a motion control system, which includes a servo motor, the drive, controller, and […]
Siemens introduces new servo drive system
With its Sinamics S210 converter designed specifically for use with the newly developed Simotics S-1FK2 motors, Siemens is offering a new and innovative servo drive system in an initial offering from 50 to 750 W. The converters come with integrated safety functions and enable rapid engineering via motion technology objects in Simatic S7-1500 controllers. They […]
