SAVER S.p.A.has developed thin-walled tubes out of high
temperature resisting epoxy-resin with reinforcement by endless glass roving (WT 2000).
The rotors of synchronous servo motors are equipped with magnets for a permanent excitation.
They need an outer bandaging that gives protection against loosening and displacement of the
single magnets in service due to vibrations and centrifugal force, as well as damages during
assembly (insertion of the rotor into the stator).
Servo motors are often used in industrial equipment such as machine tools, handling and
assembly robots, packing machines, paper and printing machines, plastic machinery, textile
machines and industrial automation.
Composite material consisting of epoxy-resin and glass roving.
Form of Delivery
Glassfibre reinforced epoxy tubes and sections, filament wound
Excellent mechanical protection of the brittle magnets during assembly
Flexible sleeving of the rotor compensating shape deviations
High performance safety armouring in service
Very low wall thickness (0.3 mm) maintaining the motor’s effectiveness
Low specific weight granting minimal impact on mass moment of inertia
Cost reduction due to reduced number of process steps:
