SINAMICS SL150

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

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.

Benefits at a glance

Low component variety to reduce capital investment and associated costs for storage and logistics.

High altitudes, temperatures and air quality, plus service friendliness for remote areas.

Integrated test routines, feedback and self-diagnostics, including thyristors, improved commissioning and tuning.

Use of standard HV cable due to the typical low switching speed of thyristors (no screened or armored cables required).
