Variable frequency drives (VFD) provide speed, torque and direction control for AC motors such as those in conveyors, fans and pumps. Soft starters provide energy-efficient motor control. DC drives provide variable speed control for DC motors, ideal for applications requiring low speed control, torque and power.
When motor control requires more flexibility than simple start/stop operation, drives and soft starters can provide speed control,
power efficiency and other advanced functionality.
Variable frequency drives (VFD) enable speed control for 3-phase AC motors such as those in conveyors, fans, pumps and shop
tools. In ratings up to 300hp, the diverse lineup includes DURApulse GS series, Ironhorse and WEG brands, with various
environmental ratings and control modes.
Soft starters are used with AC motors to temporarily reduce load and torque during start-up as compared to discrete contactor
switching. Soft starters lower energy use and reduce wear and tear on motors and connected mechanical equipment.
DC drives provide variable speed control for DC motors, ideal for applications requiring low speed control, torque, and power.
Speed adjustment is simple, typically using a potentiometer or analog input signal. IronHorse DC drives are available with either
DC or AC input voltage input, and in open frame or NEMA 4/12 or 4X enclosed versions.

Solid state soft starters provide many advantages when used instead of electro-mechanical contactors, including reduced shock
and starting stress on motors, resulting in an extended motor lifespan.
Compact WEG SSW05 and Stellar SR22 series offer a reduced footprint for solid state motor control in ratings
up to 85A (depending on series). SR22 starters are available for 1- or 3-phase motors.
Basic WEG SSW07 and Stellar SR35 series provide dependable performance on motor starts and stops, in ratings up
to 412A (depending on series) and a selection of trip classes
Full-featured Stellar SR55 series starters are fully digital, and use thyristors in all three motor phases for controlled
reduced voltage motor starting and stopping; available in ratings up to 477A, and AC or DC control voltages
