The invention describes a motor that applies the electrical
drives operating principle motors with rolling and flexible
rotor. The invention refers to an electrical motor capable
to develop high torque at low speed, with only few
rotations in a minute, fed through industrial frequency
Description
without reducing gear. The solution, entailed by this
invention, combines the design characteristics of a rolling
rotor motor with the ones of a flexible rotor motor. It has a
flexible ferromagnetic rotor that is situated on a shaft and
relies on two sliding bearings. Advantages: constructional
simplicity, low cost, operational reliability.

Patent no. Patent RO 122923 B1
The invention describes a flexible rotor-shaped glass,
which is part of construction of solar engines for operation
in tracking systems after Sun of solar converters. Flexible
rotor consists of a flexible support, cylindrical, made of a
Description
magnetic or non-magnetic material which are provided
with some ferromagnetic plates with round profile,
profiled or flat, placed on the flexible support and
provided with axial holes. Flexible rotor is driven by
motor stator, consisting of several pairs of electromagnets
which are activated successively through an
phototransducer position.
