SINAMICS SM150 Overview SINAMICS SM150 The sophisticated drive solution for single and multi-motor drives in the medium voltage General description The decades of experience that we have gained with our SIMOVERT ML, SIMOVERT ML2, drive converters, transrapid line feeder systems and traction power supply links culminate and merge in the SINAMICS SM150. SINAMICS SM150 is a high‑end drive converter for low and high speed applications. This is the reason that it is recommended for applications requiring a high dynamic performance and regenerative feedback into the line supply – generally with special motors from approx. 2.8 ‑ 30.6 MW. The water‑cooled SINAMICS SM150 drive converters, capable of regenerative feedback into the line supply, are available as either single‑motor or multi‑motor drive with well‑proven IGCT power semiconductors for medium‑voltage drive applications. For the multi-motor drives, a common DC bus allows direct energy exchange for applications that involve both motoring and generating drives. In the low power range well‑proven IGBT power semiconductors are used for single‑motor application as air cooled drive configuration. Benefits Easy plant integration due to the compact design and highly flexible configuration Simple operator control with the user‑friendly operator panel Smooth and reliable operation due to the integrated maintenance functions: the converter signals automatically and well in advance when maintenance is required and/or components need to be exchanged High ruggedness and reliability thanks to the use of IGCT/HV‑IGBT technology and fuseless design, combined with intelligent response to external disturbances Hassle‑free integration into higher-level automation systems due to PROFIBUS interface supplied as standard and analog and digital interfaces High degree of service‑friendliness due to the innovative power section design, e.g. compact phase modules and excellent accessibility of all components only applicable to the IGCT technology Ideal for direct energy exchange on the common DC bus in applications with motoring and generating drives Application Moving: Belt conveyors, ship’s drives, test stands Processing: Rolling mill drives Further, the power section is also used in Transrapid and traction power supply links.

SINAMICS SL150
SINAMICS SL150 Overview SINAMICS SL150 The cycloconverter for slow-speed synchronous and induction motors with a high torque General description 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. They set themselves apart as a result of their simple design that utilizes a relatively low number of power semiconductors. As a consequence, the SINAMICS SL150 has a high efficiency and high degree of reliability. Without any additional costs, the inherent circuit principle of the cycloconverter makes it suitable for four‑quadrant operation – i. e. driving and braking in both directions. The maximum output frequency is typically between 40 and 44 % of the line frequency. Open‑loop and closed-loop control and thyristor monitoring for the complete drive are implemented using components from the SINAMICS system. The thyristors are controlled and monitored opto-electronically via fiber‑optic cables. The heat from the power circuit is dissipated using the cabinet fans. Features High efficiency With SINAMICS SL150, low switching losses and the low loss thyristor technology ensure an extremely high efficiency (99 %). As a consequence, lower demands are placed on the cooling system. At the same time, less space is required for installation. Used worldwide The technology employed in SINAMICS SL150 has been successfully used for more than 35 years now. More than 700 units of the previous SIMOVERT D series were supplied in different versions – wherever slow speed applications demand a high power rating and the highest torque. Top marks for ruggedness and availability There are some excellent reasons why SINAMICS SL150 is extremely reliable and sets standards when it comes to ruggedness: 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 panel Feedback diagnostics of the individual thyristors in the power unit Benefits Available with air and water cooling Four-quadrant operation High short‑time overload capability: typically 200 % for 60 seconds Can be simply integrated into the plant Simple operator control and monitoring Extremely reliable Almost maintenance‑free Can be seamlessly integrated into higher‑level automation systems Air intake either through slots in the door or from below Application Rolling mills Rolling 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). Mine hoists 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 and cement crushers The 40 to 80-pole ring motors with salient pole rotors are typically operated at approx. 6 Hz (approx. 10 rpm).

SINAMICS PERFECT HARMONY GH180
SINAMICS PERFECT HARMONY GH180 Overview SINAMICS PERFECT HARMONY GH180 The Perfect Harmony of Performance, Process and Technology General description In the SINAMICS PERFECT HARMONY GH180, a series of low‑voltage cells are linked together to build the medium‑voltage power output of the drive system. With this topology, the drive can be scaled precisely for a very wide range of voltage and output power. Additionally, the SINAMICS PERFECT HARMONY GH180 offers increased availability because of its modular design and ability to bypass any one cell during operation while maintaining the full output voltage. Furthermore, the integral transformer with phase-shifted secondaries provides 18‑pulse or better input harmonic cancellation with a power factor above 0.95 under any operating conditions. This eliminates the need for input harmonic filters or power factor compensation, while completely avoiding any common‑mode voltages from being imposed on the motor. The quality of the output voltage is so close to perfect sine-wave shape that motors of literally any type – old or new, low‑speed or high‑speed – can be operated without any additional stress. Issues related to dU/dt, overheating and increased torsion vibrations are a thing of the past. Benefits Very small footprint No output transformer required – motor voltage 2.3 to 13.8 kV can be provided directly No harmonic line filters or power factor compensation required Engineered to continue operating through component failures that would completely disable conventional drives. The patented cell-based configuration maximizes availability, letting the customer determine the right time to perform maintenance, while the modular design reduces system repair time to minutes. The cell bypass option ensures automatic bypass of a failed power cell in typically 250 ms or less (less than 1/2 of a second) through a redundant bypass control that is completely separated from each power cell. The optional process-tolerant protection system (ProToPS) in combination with cell bypass supports the high reliability and availability of the SINAMICS PERFECT HARMONY GH180. Instead of tripping the drive and automatically shutting down the system due to a malfunction, ProToPS provides a hierarchical system of warnings. This control strategy allows time to evaluate the situation and respond appropriately to avoid a system shutdown. No common mode motor insulation stress – the SINAMICS PERFECT HARMONY GH180 includes an integral isolation transformer Compatible with both new and existing 1.0 service factor induction or synchronous motors from any manufacturer without any special design considerations No significant drive-induced torque pulsations – even at low speeds No need for expensive flexible couplings No cable length restrictions Application Retrofit Power generation – SINAMICS PERFECT HARMONY GH180 can ride through voltage dips or power outages Pulp/Paper – SINAMICS PERFECT HARMONY GH180 provides high output voltage at low power
