Perske spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Perske spindles and motor spindles — Perske Spezial-Elektromotoren, the German manufacturer with more than 60 years of experience in high-speed machining motors for demanding operating conditions.
Perske, more than 60 years of German expertise in special spindle motors
TLDR: Perske Spezial-Elektromotoren (Germany) has for many years specialised in the development and construction of special electric motors, with more than 60 years of experience in high-speed machining motors for demanding operating conditions.
Perske Spezial-Elektromotoren has for many years specialised in the development and construction of special electric motors, accumulating valuable experience across many fields of application that feeds into its new developments. Perske motors, designed in collaboration with the user according to the requirement profile, take account of both electrical data and environmental conditions from the design phase onwards. More than 60 years of experience with high-speed machining motors and demanding operating conditions guarantee reliability and availability. The manufacturer offers a wide range of direct drives, as well as synchronous motors without position sensors suitable as direct tool holders, used mainly in woodworking (routing, tenoning, profiling) and on applications demanding high rotation speeds.
A range of hollow-shaft and high-precision spindle motors for PCD tools
TLDR: Perske spindle motors can be fitted with a hollow shaft for spray water supply to the centre of the tool, with rotation speeds of up to 17,250 rpm, and high-precision versions specially developed for hydraulic expansion clamping systems, particularly suited to PCD (polycrystalline diamond) tools.
Perske offers motors fitted with a hollow shaft allowing spray water to be delivered directly to the centre of the tool, a feature particularly sought after when working materials that require precise cooling. Rotation speed is adjusted precisely by frequency inverter, the asynchronous motor/inverter combination additionally bringing a welcome reduction in energy consumption, with speeds reaching 17,250 rpm depending on the configuration (KNS, KCS, KS types). Perske high-precision motors are specially developed for hydraulic expansion clamping elements: the use of a reinforced high-precision ball bearing and a stiffer spindle makes it possible to achieve roundness and flatness accuracy in the micron range, particularly suited to PCD tools whose service life is thereby considerably extended, improving the profitability and availability of the machine.
