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.
Few components for any particular power rating: 9/18 MVA with 36 thyristors
Generous and rugged design
Fast fault diagnostics using an extensive, detailed message system: Trace memory for 14 signals - output at analog outputs
Fault display at the operator touch panel
Feedback diagnostics of the individual thyristors in the power unit
Low switching losses and the low loss thyristor technology ensure an extremely high efficiency (up to 99.5 %)
Lower demands are placed on the cooling system
Less space is required for installation
Technology has been successfully used for more than 35 years
More than 700 units of the previous SIMOVERT D series were supplied in different versions
Can be simply integrated into the plant
Simple operator control and monitoring
Can be seamlessly integrated into higher-level automation systems
Remote diagnostics via secure internet connections for fast service support

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).
Ore and cement 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).
For the first time, two converter types were used in one gearless drive.
