EC Fans & Drives

EXRi-50 Motor & Fan

Product Specification & Details

The EXRi50 series motor and integrated fan assembly that has been aerodynamically designed to deliver high efficiency flow rates at static operating point 25 Pascal (0.10 In-H2O) and below. It is best suited to low power condenser applications.

The EXRi50 series motor with integrated fan can be supplied with brackets or fixing via 3 x M4 Screws on rear fixing plate.

The EXRi50 motor operates at a constant speed (regardless of power supply fluctuation) and a maximum input power of 15 watts which is suited to applications with an output power range of 3 to 10 watts.

The motor has an external rotor design with the motor lamination and windings over-moulded to assist in giving maximum ingress protection.

EXRi-50 Motor & Fan

Outline Specification

  • Available in 154mm, 172mm & 200mm diameters with pre-set speeds 1330, 1600, 1850 and 2100rpm (maximum speed for 200mm diameter is 1600rpm).
  • Available in LVDC or 85VAC~265VAC 50/60 Hz (global voltage).
  • Airflow curves from our AMCA approved airflow chamber can be supplied on request.

Entry Level, Speed Controlled, Single Direction, External Rotor, Electronically Commutated Motor

Our EXRi50 motor is a ground-breaking electronically commutated (EC) motor targeted at the commercial refrigeration and small HVAC markets with multiple fixing options to suit both sectors. The EXRi50 is a Global Voltage, single speed, single direction EC motor, offering class-leading efficiency.

The EXRi50 stands out from other motors in that it comes complete with an integrated fan blade and optional fan ring. This gives the motor a compact and slim profile, making it a perfect solution for applications where space is minimal.

This energy efficient EC motor is available in three sizes consisting of 154mm, 172mm and 200mm. The motor has a full operating range of 600-3000rpm. However, standard units were designed with the most common speeds used in refrigeration which are available in one of four pre-set speeds of1330, 1600, 1850, or 2100rpm. The EXRi50 is competitively priced allowing OEMs to select a Global Voltage motor already equipped with an integrated fan blade ultimately reducing the number of SKUs an OEM has to carry. Additionally, the motor removes the need to source and fit a separate fan blade, further reducing the drain on financial and labor resources.
