What are motors and drives?
Motors transform electrical and magnetic energy to motion and include a wide array of technologies, designs, sizes, form factors and standards for many applications. Drives control the motion of motors and other actuators and can be integrated with the motor or other actuator, stand alone, and can exist as a software application in a controller.
A properly maintained variable frequency drive (VFD) can provide decades and cost-effective service. Making VFD inspections and maintenance part of facility oversight can improve outcomes.
Motor innovations: Advanced motor technologies influence motor form factors, performance, and efficiencies. Examine how these technology advances can help with your next set of applications.
Five trends on buying and, specifying motor drives for industrial automation applications.
Think Again: Remote monitoring, sensors, analytics and real-time intelligence is helping those who manufacture, use, and repair motors and attached critical assets to avoid downtime with prescriptive maintenance technologies, says EASA and Plant Engineering research.
Temperature, power quality, and torque all are strong indicators of a motor's health.
Stepper motors remain popular for industrial motor applications because they are low-cost, rugged, simple, have high torque at startup and low speeds, require little maintenance, and they can operate in an open loop control system.
Variable frequency drive (VFD) development is shifting focus away from general-purpose motor controls that are already meeting market demands toward reduced installation costs. Consider industrial VFD installation time, VFD installation space and VFD harmonics.
