EMX-D

The Emotron EMX-D drive system is a complete range of speed controlled drive systems especially designed for rotary heat exchangers. Each system consists of a motor and a corresponding electronic controller.

The latest EMX-D has the same functions as the previous versions, by the design is based on the advanced Emotron FDU Variable Frequency Drive.

All functions are controlled on the built-in display. This makes operation and troubleshooting very easy. The motor can run in both directions, and to further support an easy installation, no adjustments or settings are required to get the drive system into operation

 

EMX-D Features

  • Advanced user-interface for complete control of settings and operation
  • High switching frequency for quiet operation
  • A wide speed range for maximum usage of the high efficiency in the heat exchange rotor
  • Easy handling since no adjustments or settings are required
  • The control signal is proportional to the efficiency of the heat exchanger rotor
  • Selectable direction of rotation
  • Extensive protection against short circuit, overloading, etc.
  • Holding torque - prevents involutary heat recovery

EMX drive systems are available for rotors up to 18 feet in diameter

speed control of rotary heat exchangers

EMX drive systems from Emotron are specifically designed for speed control of rotary heat exchangers. Models include complete drive systems with an integrated rotation sensor, compact control units for temperature control, and a complete drive system for large rotors – up to 18 feet in diameter.


emx-p

The Emotron EMX-P is a small and flexible control unit specially adapted for speed regulation of smaller heat exchangers. A motor with gear and tachometer from Panasonic or Oriental Motor (25 W or 40 W and mx 0.7A) are intended to be connected to the control unit. Both the motor and the control unit are easily placed inside the heat exchanger housing.

EMX-P offers many functions that ensure safe and reliable operation. The control unit uses a new technology that provides more effective control with smaller losses and higher torque. Greater speed range gives better recovery and therefore less temperature oscillation.

 

EMX-P Features

  • No tuning
  • Less wear – soft start/soft stop
  • Less temperature oscillation – large speed range
  • Automatic purging operation
  • Rotation monitor with external rotation sensor
  • Full control of speed with tachometer feedback
  • Selectable types of speed control
  • Linearization function – control signal contra rotor efficiency
  • Control inputs have common galvanic insulation from the mains supply

EMX-R

The EMX-R drive system is a complete range of speed controlled drive systems for rotary heat exchangers. Each system consists of a motor and a corresponding electronic controller.

What makes EMX-R unique is that it’s equipped with an integrated electronic rotation sensor, RotoSens™, which eliminates the need for a mechanical sensor. The system can also easily handle a conventional mechanical rotation sensor if so desired.

As with previous generations, the current EMX-R drive systems are based on the switched reluctance (SR) motor technology.

The SR technology allows the EMX-R motor to drive exchanger wheels with diameters up to 3.5m (11.5ft.) without any need for a gearbox.

 

EMX-R Features

  • Robust motor without gear or fan
  • Integrated electronic rotation sensor – eliminates the need for mechanical sensors
  • High efficiency – no gearbox losses
  • A wide speed range for maximum usage of the high efficiency in the exchanger wheel
  • Easy handling since no adjustments or settings are required
  • Selectable direction of rotation
  • Integrated motor cable
  • Extensive protection against short circuit, overloading, etc.
  • Holding torque – prevents involuntary heat transference

SR Technology

Switched reluctance (SR) motors are used in Emotron's market-leading drive system for rotary heat exchangers, first introduced in 1984. The company holds several patents for the design, control, and monitoring of SR motors.
