Electromotor 1365 KW SCHORCH

Overview

Electromotor 1365 KW SCHORCH is a high-voltage industrial squirrel-cage induction motor engineered for continuous heavy-duty service as a prime mover for large compressors, pumps, and fans. Rated at 1365 kW and designed to operate on a 6.6 kV supply, this motor is built by ATB Schorch, a German high-voltage motor specialist with a long-standing reputation in the oil and gas, mining, water treatment, and heavy manufacturing sectors.

As the an experienced supply partner for SCHORCH, Seven Star LLC proudly supplies this 1365 kW high-voltage motor and the wider SCHORCH high-voltage motor range to industrial operators across Oman and the GCC. Units are sourced on request for plant operators, with ATB Schorch’s manufacturer documentation.

Operating Principle

As a squirrel-cage induction motor, the 1365 kW SCHORCH unit operates on the principle of electromagnetic induction: a rotating magnetic field is established in the stator windings by the supplied three-phase 6.6 kV current, and this field induces current in the rotor’s squirrel-cage conductor bars, which in turn generates the torque that drives the rotor to turn. At the high power rating of this unit, precise stator winding design and insulation quality are critical to sustaining efficient, stable torque delivery under continuous full-load operation.

The motor’s thermal design and cooling system work together to manage the substantial heat generated at this power level, maintaining winding temperatures within safe limits across long, uninterrupted duty cycles. This combination of induction-motor simplicity and robust thermal management is what makes high-voltage squirrel-cage motors like this one the standard choice for driving large rotating loads in continuous industrial service.

Engineering Design of the Electromotor 1365 KW SCHORCH

The Electromotor 1365 KW SCHORCH is built with a reinforced frame and casing designed to support stable, low-vibration operation under sustained high-torque loading, along with advanced winding insulation and a cooling system engineered to maintain efficient thermal performance at full rated output. Its frame design supports straightforward mounting and integration into existing driven-equipment setups, whether coupled directly to a compressor or pump shaft or connected through an intermediate gearbox.

Thermal protection devices embedded in the stator windings, along with a reinforced casing, provide the safety margins expected of a motor operating continuously at 6.6 kV and this power rating. Compliance with international IEC standards for high-voltage motors ensures the unit meets recognized electrical safety and performance benchmarks accepted across Oman’s industrial regulatory environment.

Industrial Applications

Across Oman’s oil and gas, petrochemical, mining, and water treatment sectors, motors of this class drive large centrifugal compressors, process pumps, and induced-draft fans where continuous, reliable high-torque output is essential to maintaining production. Facilities in the Sohar and Salalah economic zones, along with major processing plants across the Sultanate, rely on high-voltage SCHORCH motors to power critical rotating equipment where an unplanned motor failure carries significant production and safety consequences.

Working closely with plant engineers in the region, Seven Star LLC distributes this 1365 kW motor and the wider SCHORCH high-voltage motor range to EPC contractors, plant engineering teams, and industrial equipment integrators throughout Oman and the GCC, supporting both new plant construction and the replacement of aging or failed high-voltage motors on operating facilities.

Standards, Cooling and Degree of Protection

High-voltage machines of this class are built and verified against the IEC 60034 series, and the clauses that govern a purchase decision are worth stating plainly. IEC 60034-1 defines rating and performance, including the duty types – continuous running duty S1 is the norm for compressor, pump and fan drives of this size – and the tolerance bands within which the guaranteed output, current and efficiency must fall. IEC 60034-5 defines the IP degrees of protection, IEC 60034-6 the IC cooling method codes, IEC 60034-7 the IM mounting arrangements, and IEC 60034-14 the permissible vibration magnitudes at the shaft height and speed concerned. A purchase specification that names the required IP, IC and IM codes explicitly removes most of the ambiguity that otherwise emerges during factory acceptance testing.

Cooling method is the single most consequential of those choices for a Gulf installation. An IC 411 or IC 511 air-to-air cooled machine rejects its losses to ambient air through a top-mounted heat exchanger, and its winding temperature therefore tracks site ambient directly. An IC 81W air-to-water cooled machine rejects to a water circuit and is far less sensitive to a 48 °C summer design ambient, at the cost of requiring a reliable cooling water supply and the associated leak detection. Because standard IEC ratings assume a 40 °C ambient and an altitude of up to 1,000 m, any SCHORCH machine ordered for an Omani site should have its rating confirmed against the actual site design ambient, and a derating or a higher temperature-rise class agreed with the manufacturer before the order is placed rather than discovered during commissioning.

Auxiliaries, Protection and Confirming the Specification

Motors at this power level are never supplied bare. The auxiliaries that should appear on the datasheet include Pt100 resistance thermometers embedded in the stator windings and fitted to each bearing, anti-condensation space heaters energised whenever the machine is at standstill, a bearing insulation arrangement at the non-drive end to interrupt shaft circulating currents, and terminal boxes sized and certified for the cable entry and short-circuit withstand of the site switchgear. Where the machine is started direct-on-line, the starting current and the permitted number of consecutive cold and hot starts must be checked against both the supply transformer impedance and the manufacturer’s stated thermal withstand, since it is the start duty rather than the running duty that most often limits a large high-voltage motor in practice.

SCHORCH publishes its high-voltage machine programme as covering roughly 1,000 to 4,000 kW at 6,000 to 11,000 V, with individual machines identified by series and frame designations rather than by output alone. Because a rating such as 1365 kW describes a duty point rather than a catalogue model, Seven Star LLC asks clients to supply the nameplate details – type designation, serial number, frame, pole count, voltage, frequency, cooling and mounting codes – when enquiring against an existing machine. That allows a genuine like-for-like replacement or a properly engineered upgrade to be quoted, rather than a nominally equivalent motor that does not match the existing foundation, coupling, terminal box orientation or protection scheme.
