To make any mechanical repair we refer to the OEM original dimensions, and if not available we use standard files and tolerance tables taking into consideration (application, material of parts to be machined and the speed of the machine).
Machining technique also to be selected according to the application and material of the part to be machined.
Our rotor balancing range from 50 to 5,000 kg using the latest Schenck technology and are balanced to relevant ISO standards. On completion, you receive a comprehensive balancing report that documents compliance with these international standards.
Our Schenck 50 kg and 5,000 kg balancing machines are fitted with the latest CAB900 measuring system. Plus, our balancing machines are fitted with a Bentley Nevada vibration system so we can identify the vibration base line prior to installation of the rotor.
PPS SERVICES ALL INDUSTRIAL MOTOR BRANDS, INCLUDING:
PPS is capable to do complete overhauling for all kinds of motors up to 11KV AC and all sizes of DC motors
PPS ensures for you the best quality and the shortest of overhauling.
The following three steps mandatory in the overhauling scope:
Increase insulation, machining for slip rings/commutator, rotor balancing, change bearing using original bearings (SKF or FAG are the only recommended).
PPS is Capable to rewind all sizes of motors up to 11 KV AC using High quality rewinding materials
also Capable to rewind DC motors
PPS strategy to rewind as same as the original winding data without any kind of modification or re-design
-AC induction motors – squirrel cage & wound rotor
-AC synchronous motors – brushless & slip ring
-DC motors – permanent magnet, series, shunt, compound
-Specialty motors – vertical, hermetic, nuclear, explosion-proof, servo
-Voltage ratings from low voltage to 11,000 VAC / 1,000 VDC
