DC MOTOR EVALUATION
Start Your Elevator Modernization
Project off Right
Updating older elevator machines to modern technology
can significantly reduce energy costs. DC machines that are
properly maintained and in good working order can provide
excellent ride quality and years of additional service.
Preparation is key to ensure that an elevator modernization
project is successful. Magnetek recommends that a motor
analysis and repair company perform a DC motor evaluation
before building owners begin a modernization project.
BENEFITS
• Become aware of problems that require immediate
repair for continued service

Magnetek Elevator Drives Provide
New Life for Your Elevator
Once you ensure your elevator motors are ready
for a modernization, Magnetek drives are the optimal
choice for a successful project.
Our Quattro® DC regenerative drives greatly reduce
energy consumption, saving as much as 25% over SCR based DC
drives and as much as 45% over motor generator sets in gearless
DC installations. Many utility companies offer energy saving rebate
programs for reduced peak and average power demand and for
clean harmonics. Quattro DC eliminates the need for a motor
generator, and offers better performance and handling capacity.
Magnetek’s proven track record, technical expertise,
and superior customer service make us the world’s leading
source for high-performance, built-to-last DC elevator drives.
With over 35 years of innovation, you can count on
Magnetek for your drive modernization solution.
