Синхронные серводвигатели MKE - для взрывоопасных зон


  • Maximum torques up to 190 Nm
  • Maximum speeds up to 9,000 rpm
  • Encoder systems for a wide and diverse range of applications
  • Compliance with ATEX and UL/CSA

The MKE range of motors are specifically designed for use in production plants susceptible to explosive mixtures of air and flammable gases, vapors, mist or dust.

Within the broad range of torques up to a maximum of 190 Nm, there is a choice of various sizes of motor with flameproof enclosures. Needless to say, all are ATEX certified and/or UL/CSA compliant. These motors can also be supplied with a range of options – holding brake, keyway and single- or multi-turn encoder systems.

Internationally recognized certification
MKE motors have been certified by the German metrology institute providing scientific and technical services, the PTB Braunschweig, in accordance with Directive 94/9/EC – ATEX95 (II 2 Gd IIB T4 or rather II 2D Ex tD A21 IP6x T135°C). MKE motors based on the American standard (UL/CSA) conforming to Class I, Groups C and D as per UL508C, UL674 and UL1446, have been certified directly by Underwriters Laboratories Inc. (UL) in the USA.
