3. General description

Grundfos MGE 71, MGE 80, and MGE 90 are frequency-controlled permanent-magnet motors for single-phase or three-phase mains connection, incorporating a PI controller. They can be connected to an external sensor and setpoint signal for closed-loop control, or used in an open-loop system where the setpoint signal acts as a speed control signal. These motors are intended for machines with a square torque characteristic, such as ventilators and centrifugal pumps.

The motors feature a control panel available in various versions (see section 8. User interfaces). Detailed motor settings are made using the wireless Grundfos R100 remote control or Grundfos GO Remote. Important operating parameters can also be read via these devices.

The motors include a functional module, available in various versions with different inputs and outputs (see section 6.5 Functional modules). An optional Grundfos CIM module can be fitted for data transmission to external systems (e.g., BMS or SCADA) via fieldbus protocols.

3.1 Radio communication

This product features a class 1 radio module for remote control, usable in all EU member states without restrictions. For use in the USA and Canada, refer to page 35. Some product variants, particularly those sold in China and Korea, may not include a radio module.

The motor can communicate with the Grundfos GO Remote and other MGE motors of the same type via the built-in radio module. An external antenna may be required in some cases, and only Grundfos-approved antennas should be used, installed by an approved technician.

3.2 Battery

The FM 300 functional module contains a Li-ion battery compliant with the Battery Directive (2006/66/EC), free from mercury, lead, and cadmium.

4. Identification

The motor is identified by its nameplate, located on the side of the terminal box (see Fig. 1, pos. A). Figure 2 illustrates the nameplate layout, with numbered positions corresponding to the table below, detailing components such as type designation, product number, supply voltage, rated power, and manufacturer information.
