What’s the difference between BLDC and synchronous AC motors?

December 17, 2015 By Danielle Collins Leave a Comment

BLDC and synchronous AC motors

The short answer is: brushless DC (BLDC) and synchronous AC motors are similar in construction and operation. Some manufacturers and experts even group them together as similar technologies, in the category of  “permanent magnet synchronous motors.” Their key difference, however, lies in the stator coil windings and resulting back-EMF waveform of each motor. This gives them distinct performance […]

Motion Trends: New motor breeds are smart, connected, and compact

April 5, 2019 By Lisa Eitel Leave a Comment

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 […]

What’s the difference between an EC motor and a BLDC motor?

July 5, 2018 By Danielle Collins Leave a Comment

EC motor

Deciphering motor terminology can be frustrating, especially when comparing the operation and performance of various motor types. For example, some motors are characterized by their speed (synchronous or asynchronous) while others are characterized by their commutation method (brushed or brushless). And then there’s the issue of whether the motor is operated with AC or DC […]

What’s the difference between cogging torque and torque ripple?

June 25, 2018 By Danielle Collins Leave a Comment

cogging torque

The basic operation of an electric motor relies on the interaction between the rotor’s permanent magnets and the stator’s energized windings. But even when the motor is not powered and no current is flowing though the windings, there is a magnetic attraction between the permanent magnets of the rotor and the ferromagnetic teeth of the […]

Selecting a servo drive: 9 things you need to know

April 25, 2018 By Danielle Collins Leave a Comment

selecting a servo drive

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 […]

BLDC motor: Marketing jargon or more?

September 1, 2017 By Miles Budimir Leave a Comment

dc motor

The term brushless dc motor (or BLDC motor) is common lingo in the industrial world. The question is, does it make any sense? Perhaps a little history can help here. The first brushless dc motors were marketed as such because they functioned as drop-in replacements for brush dc motors. There were a number of technological […]

Trends in electric motors part one: Market shifts towards smart solutions

April 18, 2017 By Lisa Eitel Leave a Comment

This year in motor design there’s been an uptick in three trends. Disposable medical devices, new consumer products, and the automation of humbler tasks are driving demand for affordable and miniature-motor options. (Read more about motor miniaturization in the second installment of this two-part Motion Trends series on electric motors here.) A related trend towards […]

FAQ: What are ways to avoid torque ripple in DC motors?

February 8, 2017 By Danielle Collins Leave a Comment

torque ripple

Torque ripple—variations in torque production during shaft revolution—is an undesirable effect that occurs in permanent magnet motors, preventing smooth motor rotation. Torque ripple is generally defined as non-linear torque production of an energized motor. Cogging torque—a phenomenon similar to torque ripple—is torque produced by the attraction between the permanent magnets of the rotor and the […]
