SLIP RING MOTORS

Asynchronous ring motors are the heart of many drive applications in the high Power segment. They are used in the raw materials industry as well as minerals and other stones or also in the agglomeration industry such as obtaining cement, lime and plaster for the drive of Crushers, roller presses and mills but also for the Large fan drives, Pumps and other types of drives such as extended conveyor belts.

EXPLOSION PROOF ELECTRIC MOTORS

HELMKE has been supplying Electric Motors for service in explosive areas for many years. 

Zone 2 ex nA Antispark 
Zone 1 ex e increased security 
             Ex d explosion proof 
             Ex p overpressure shield   

    

Variable speed drives (motor and frequency converter) for Zone 2 operation. We can test and certify as a unit in our test room. We have achieved the following pre-conditions for the modification of motors with Ex protection:

​

  • Quality Management System according to ISO 9001:2000 

  • Production subject to additional audit Ex according to 94/9/EC (ATEX) 

  • Specialized staff 

  • Achieving the corresponding test possibilities 

  • Narrow collaboration with Certifying Organizations

​

Three phase short circuit motors, Explosion Proof protection, Medium voltage type DDOR ( EE x d II CT4 ) & DEDOR ( EE x de II CT4 ). Helmke Motor Series provide reliability and safety.

FREQUENCY CONVERTERS - DRIVES

We develop customised solutions for complete electrical equipment composed of transformer, frequency converter and motor:

  • Low voltage: Voltage Range 230 V up to 690 V, power range 0.55 kw to 2800 kw

  • Medium Voltage: Voltage range 2.4 kv to 13.8 kv, power range 0.2 MW to 25 MW

  • Project analysis and Planning (organization and project follow-up)

  • Project and study of drives systems (system solutions, detail engineering torsional analysis)

  • Project development (Control of Lead Times and Terms)

  • Evidence and documentation of the project under the supervision of all of the components and their function (system test on the own test bench)

  • Acceptance of responsibility for the electric drive system

  • Containerization for each environment: air-conditioned, ready-to-connect, tested and parameterized
