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.

Lower price of the construction in case of installing the drive in new buildings, which emerges from the possibility of mounting the drive direct in the lift pit or the adjacent sites.

Minimum maintenance requirements during the operation. The design and manufacture of the drive provides for the minimum possible need of periodical service-related interventions. The need of regular exchanges of oil fillings, clutch segments and the need of brakes adjustment is eliminated thereby.

Ecology requirements: During its service life the drive is fully recyclable. The use of permanent oil fillings eliminates the generation of dangerous wastes and the need of handling them during the entire service life of the drive.

Low energy consumption of the drive is one of its most significant advantages as it contributes considerably to a

shortening of the return time of the costs associated with its use.

Enhancement of the run comfort and a precision stop.

The SLP drive design is explicitly specified by the type and numeric code as follows:

As standard, the motors are supplied with friction wheels of 500 mm diameter to accommodate 6 ropes of 10 mm diameter.
