Description

Overview

The Schorch KA2454X-BJ01G (listed as Electromotor 900 KW SCHORCH) is a three-phase high-voltage squirrel-cage induction motor manufactured by ATB Schorch GmbH, Mönchengladbach, Germany. The unit is listed with a rated output of 900 kW at 6.6 kV, 92 A and 1494 rpm, which corresponds to a 4-pole machine on a 50 Hz supply.

ATB Schorch produces high-voltage motors from about 160 kW upward in rib-cooled, tube-cooled and modular designs for safe and hazardous areas. Enclosure, cooling method and any explosion-protection marking of this individual unit are defined by its order configuration and must be confirmed from the nameplate before a replacement is specified.

How the Electromotor 900 KW SCHORCH Works

A three-phase squirrel-cage induction motor such as the Schorch KA2454X-BJ01G has a stator winding connected to the 6.6 kV supply and a rotor made of conductive bars short-circuited by end rings. The three-phase stator current produces a rotating magnetic field. At 50 Hz a four-pole machine has a synchronous speed of 1500 rpm. The rotating field induces currents in the rotor bars, and the interaction between these currents and the field produces torque. The rotor always runs slightly below synchronous speed; the difference is called slip. With a rated speed of 1494 rpm, the slip of this motor at full load is about 0.4%, which is typical of large, efficient high-voltage machines.

Because the rotor has no brushes, slip rings or commutator, a squirrel-cage motor needs very little routine electrical maintenance. The main wear items are the bearings, and the main long-term risk is ageing of the stator insulation.

Selection & Replacement Guide

When an existing Electromotor 900 KW SCHORCH must be replaced or a spare is ordered, matching the power, voltage and speed is not enough. The following nameplate and installation data should be checked:

Item	Why it matters
Full type code and serial number	Identifies the exact design and allows the manufacturer to trace the original configuration.
Frame size and mounting arrangement (IM code)	Determines foundation bolt pattern, shaft height and coupling position.
Cooling method (IC code)	Rib-cooled, tube-cooled (air-to-air) and air-to-water designs have different dimensions and auxiliary connections.
Degree of protection (IP code)	Must suit outdoor, dusty or humid locations.
Explosion protection marking	Required where the motor sits in a classified hazardous area, for example Ex e, Ex d, Ex p or Ex n types.
Bearing type and lubrication	Rolling or sleeve bearings change the maintenance regime and spare parts.
Accessories	Winding and bearing temperature sensors, anti-condensation heaters and vibration probes must be wired into the existing protection system.
Starting method	Direct-on-line, soft starter or variable-speed drive operation affects the winding and bearing insulation design.

Installation & Maintenance

High-voltage motors in the 900 kW range are normally installed on a rigid steel or concrete foundation and coupled to the driven machine. Good practice includes:

Precision shaft alignment, ideally with laser tools, after the motor and driven machine have been bolted down, and a recheck once the machine reaches operating temperature.
Insulation resistance and polarisation index tests on the stator winding before first energisation and after long storage or idle periods.
Use of anti-condensation heaters when the motor is stopped, which is especially important in humid coastal areas.
Bearing lubrication with the grease type and interval given on the motor lubrication plate.
Regular vibration and temperature trending to detect bearing wear, misalignment or rotor bar problems early.
Periodic inspection of the terminal box, cable glands and earthing connections.

Typical Applications in Oman & the GCC

Motors of this size and speed drive large centrifugal pumps on crude oil, product and water pipelines, injection pumps in oil fields, process compressors in gas plants and refineries, cooling water pumps in power and desalination plants, and large fans in cement plants. High ambient temperatures in the region make it important to check whether a replacement motor is rated for the actual site ambient, because derating may be required above the standard design temperature.

About brand

Schorch is the specialist builder of large high-voltage motors, founded in 1882 in Mönchengladbach, Germany, and trading today as ATB Schorch GmbH. Its machines drive compressors, pumps and fans in refineries, chemical plants, power stations and ships, many of them explosion-protected for hazardous areas.

Seven Star LLC is an independent supplier in Muscat. We list Schorch motors from 900 kW to 2,300 kW and source Schorch motor spare parts for users in Oman and the GCC, against the motor's nameplate data.

Schorch company profile

Established	1882, Mönchengladbach, Germany, as MAX SCHORCH & Cie, founded by Max Schorch
Early history	Dynamos and arc lamps from 1885. The company became a public company in 1900 and started building three-phase machines.
Company today	ATB Schorch GmbH, Mönchengladbach
Product families	Low- and high-voltage asynchronous (induction) motors and generators, in standard and explosion-protected versions, plus repair and retrofit of motors of any make
Explosion protection	IECEx-certified machines with increased safety "e", flameproof "d", pressurized "p" and dust protection by enclosure "t"

Milestones

1882: Max Schorch founds MAX SCHORCH & Cie in Mönchengladbach.
1885: Production of dynamos and arc lamps begins.
1900: The company becomes a public company and starts building three-phase machines.
Today: ATB Schorch GmbH in Mönchengladbach builds LV and HV motors and generators, including explosion-protected designs.

Schorch motors we list

Motor	Type	Typical drive
900 kW	High-voltage induction motor	Process pumps, fans and smaller compressors
1,365 kW	High-voltage induction motor	Pipeline and injection pumps, compressors
1,680 kW (KV6535B-AA06)	High-voltage induction motor	Compressors and large pumps
2,300 kW	High-voltage induction motor	Gas compressors, boiler feed and large cooling water pumps
KN series	Low-voltage induction motor, IP23	Indoor drives where open drip-proof cooling is acceptable

Large motors like these are built to order. The type code on the nameplate (for example KV6535B-AA06) together with the serial number identifies the exact frame, cooling method, bearings, terminal box and explosion protection, so a replacement or spare part is always matched to that data.

Where Schorch motors are used

In Oman and the GCC, Schorch high-voltage motors drive compressors, crude and water injection pumps, cooling water pumps and fans in oil and gas fields, refineries, petrochemical plants, power and desalination stations, often in hazardous areas where an Ex "e", "d" or "p" motor is required.

Ordering Schorch motors and spares: what we need

Send a photo of the nameplate or the type code and serial number, the rated power, voltage, frequency, speed, mounting arrangement and the explosion protection marking. For spare parts (bearings, seals, fans, terminal boxes, cooler parts or space heaters), add the part description and, if available, the item number from the motor documentation.
