SINAMICS SL150

The cycloconverter for slow-speed synchronous and induction motors with a high torque

sinamics sl150

SINAMICS SL150 cycloconverters with thyristor stacks are the optimum choice when it comes to continuously controlling the speed of high-rating induction and synchronous motors with a high torque and low stator frequencies. They are implemented as three-phase thyristor bridges in a 6 or 12-pulse connection. Ideally suited for powering mine winders, conveyors, grinding mills and excavators due to is rugged design.

Rolling mill drives that run continuously typically have 6-pole cylindrical rotor synchronous motors with a rated frequency of approx. 7 Hz (approx. 140 rpm) and a maximum frequency of approx. 20 Hz (approx. 400 rpm), while the large hot reversing stands are equipped with 12-pole motors with a frequency of approx. 5 / 10 Hz (approx. 50 / 100 rpm).

Numerous applications such as crushers, excavators, hoists and both geared and gearless conveyors and mills, are supported by the SINAMICS SL150 drive.
- Mine hoist drives are equipped with 12 to 16-pole synchronous motors with salient pole rotors with a rated frequency of approx. 5 to 10 Hz operating at speeds from about 50 to 90 rpm.
- Ore crushers featuring a SINAMICS SL150 also typically feature 40 to 80-pole ring motors with salient pole rotors and are usually operated at approx. 6 Hz (approx. 10 rpm).
