Applications

Universal motors operate on both AC and DC power and are widely used wherever high speed and compact form are needed. At 10,000 RPM, this class of motor is typical in portable and benchtop equipment such as grinders, polishers, mixers, blenders, drill drives, and various industrial hand tools. Thompson Chemtrex used Grovbar motors in chemical mixing and processing equipment, where precise high-speed agitation is required. Surplus replacement motors of this type are sought after for equipment repair, custom fabrication, and OEM maintenance applications. The universal motor design has been a staple of portable and light industrial tooling since the mid-twentieth century and remains in active use today across food service, laboratory, and light manufacturing environments.
