Type “DM” 3 Phase AC Solenoid Magnetic Drum Brake Spring applied / Electrically Released

Type GDM -AM, 3 Phase Magnet Brakes:

Brake Size:

  • This must be selected to give required braking torque and also be suitable to dissipate heat generated during braking operations without over heating.

Brake Torque:

  • This is often negated to drive motor torque by an arbitrary service factor, typically 100% full load torque for crane travel and similar inertial loads which tend to be self-stopping or 150% for crane hoist and other overhauling loads.

Continuous Rating:

  • Coils operate at class ‘B’ temperature while contiguously energized.

Intermittent Rating:

  • Short time rated for up to 120 operations per hour max. 5 min. in 15 min. (33% on).

Flameproof Magnet (Hazardous Locations):

  • Some magnet sizes available with flameproof enclosures (Type AF) to BS229 for Group I,II, & III. Allow +40% weight for AF type, please contact us

Line Current:

To calculate line current use the following equation:
LC = KVA / (0.00173 x LV)
Where LV = line voltage
(see coil table)
