 Lift
motors of range ATM
The three-phase asynchronous lift motors are intended
for drives of lift machines.The three-phase asynchronous squirrel-cage
motors of range ATM are equipped with degrees of protection IP10 and IP20,
internal cooling IC01 and with an option of adding supplementary cooling
for higher number of starts. The employed insulation system corresponds to
the thermal insulation class F. Construction parts are made of cast iron.
Terminal box and its cover are of aluminum alloy. In basic design, the
terminal box is situated on top of the motor, with an option of turning
the terminal box through 180o. Mechanical design of the frame
enables the terminal box to be transferred to the right or left side of
the motor. The motors feature low noise and low severity of vibration.
Mounting dimensions comply with the standard IEC 60072-1

 Gearless
drive type SLP 315
The SLP lift drive is a gearless drive that consists
of a driving unit, braking system and friction wheel. The whole drive is
positioned on a single shaft, which enables the mounting and fixing parts
to form one compact unit. The driving unit stands for a three-phase
permanent magnet synchronous motor. The motor frame serves as a carrier
construction of the entire motor as well. On the frame there are mounting
holes and fixing spots for brakes and rope holders. The frame upper part
accommodates the terminal box that ensures central connection of all
electric components participating in the functioning and protection of the
drive. The braking system is composed of two independent d.c.
electromagnets with compression springs. Emergency brake release is
possible by the use of a stand-by source or by manual releasing of the
brake. Brake release control is carried out by a micro switch that may
also provide a trigger pulse to change the hold-on voltage of the brake.
The friction wheel is made of cast iron, while its diameter, the number
and profile of rope grooves can be modified by the customer's
requirements. The drive is fed from a solid state frequency converter,
which provides a continuous speed control over the full range of operating
speeds. The motor winding is equipped with a built-in thermal protection.

 Electric
Generator SGT
The generators, types SGT 215-12D and SGT
215-12Y replace the original generators of model 5506 205 and 5506 206 in
complete volume of electric parameters and the mechanical measures.
The generator is intended for operating
as a power supply to be used on railway carriages. It is a 3-phase
claw-pole synchronous generator driven by a gear unit attached to the axle
bearing by a flange. The three-phase current generated on the run by the
generator in co-operation with regulator is used, after rectification, for
supplying electrical appliances and for charging carriage accumulators.
