OJ-MRHX stepper motor

OJ MRHX is a series of stepper motors dedicated to rotary heat exchangers

The MRHX stepper motor is ideal for use with the DRHX drive. Together, they form a system designed especially for rotary heat exchangers. The system enables accurate and silent control of rotary heat exchangers in ventilation systems.

The stepper motor provides an even torque curve throughout the entire speed range from 1 to 250 rpm. The rotor can be accurately controlled over a wide operating range, resulting in energy-optimised heat redovery and precise temperature control. 

Direct drive
To achieve correct rotor speed, simply mount a suitable pulley on the shaft of the MRHX stepper motor. Energy loss is reduced due to the non-gear solution, which means that motor power is utilized to its maximum. This also helps prolong the life-span of the equipment and minimize service costs.

The product range covers four different motor sizes to ensure optimum use of application workspace. The 14 Nm motor size will be available from November 2017.

Product features:

  • 2Nm to 14Nm
  • Sealing grade of IP 54
  • Silent operation
  • Three-phase supply
