Facts about Regal

Our Heritage
• Established in Wisconsin, USA in 1955. Officially listed on the NY Stock Exchange in 2005.
• Born in 1913, Marathon have gained over 100 years experience in design and manufacture of
electric motors and generators.
Marathon has built their legacy on innovation combining magnetics and motors into a single
leading technology. Their use of MagnologyTM has led to the motor industry’s first axial & radial
flux motors used in pumping applications.
• Unico has been providing innovative motion control solutions since 1967. With operations in 10
countries, Unico drives incorporate application specific features & functions not found in general
purpose drives.

designed to dissipate the optimum amount of heat with the
lowest airflow over the motor. This helps to ensure that
windage noise is minimized. Adequate spacing between
ribs is maintained to lessen the possibility of blockage due
to the build up of dirt.

Shafts are manufactured from high quality steel and
adequately proportioned to provide strength and rigidity

accurate bearing fit and positioning. Keys are provided
with each motor.
