general characteristics general information MGM brake motors are asynchronous threephase totally enclosed fan cooled motors (TEFC). The motor brakes in case of power supply failure. The braking action is always obtained through a very quick and precise stop and it guarantees a safe and prompt intervention in case of power failure. The braking action is obtained without shaft axial sliding and it provides equal braking torque in both directions of rotation. MGM brake motors are particularly suitable for hoist and traverse machines, tooling ma- chinery, automatic and transfer machinery in...

The table below shows the production range. For single speed motors, starting from 0.12 kW, only those in BAX, BAHX, BMX version for continuous duty and efficiency class compliant with European regulation EU 2019/1781 are listed. Further powers are available for the BA and BM series motors in the 'Enhanced Power' version for intermittent duty only (see page 52). Motor type Note: all motors indicated in the table above can also be produced as standard asynchronous three phase motors without brake (SMX or SM Series)

motor identification nameplate Every motor is provided with an identifying nameplate, on which specific motor information is given. Motor nameplates are shown below with motor data and explanatory notes. The nameplate shown on the left is used for single speed motors while the nameplate on the right is used for two speed motors. A QR code is on the nameplate of each motor through which you can link to a specific page and access various documents including the use and maintenance manual, electrical connections diagrams and technical data sheets relating to the specific series of motors. Duty...

general characteristics type of construction and mounting The table below shows the most important types of mounting arrangements according to EN 60034-7 standard. Two systems of classification are provided: code 1 (the alpha-numeric designation) and code 2 (the numeric designation). Horizontal shaft mountings Foot mounted motor, feet down. Foot mounted motor. Feet right (viewed from D-End). Flange mounted on D-End side. Foot and flange mounted motor. Foot mounted motor. Feet left (viewed from D-End). Foot mounted motor. Feet up (viewed from D-End). Face mounted. Flange with threaded holes...

The enclosure rating of the motor has to be suitable for the environment conditions the motor operates in. According to the IEC34-5 (EN 60034-5) standard the designation of the protection degree is expressed by means of a symbol made up of two letters (IP) followed by a two digit number. The first digit indicates the protection degree provided by the motor enclosure in contact with parts in motion, electrically energized, or against the penetration of foreign bodies. The second digit indicates the protection degree of the motor enclosure against damages caused by the liquid infiltration....

general characteristics All MGM brake motors are equipped with double seal ball bearings. The bearings are lubricated for life with a considerable grease reserve, the seals are made of synthetic rubber resistant to oil and to wear. On MGM brake motors belonging to BAX and BMX series can be installed bearings with a “Z" shield instead of a “2RS” one. Frame size Bearing type The nominal bearings lifetime is expressed in working hours reached or exceeded by 90% of the same bearings under certain test conditions. The key parameters that affect bearings life are the load applied on the bearing,...
