These Marathon brake motors are generally AC motors. They are available in both one and three-phase configurations, while DC motors are available in single-phase models only.
Marathon three-phase braking motors are used in crushers, cranes & hoists, plungers and conveyors.
Yes, a three-phase motor supplies thrice as much power as a one-phase motor, while only needing one additional wire (i.e. three wires instead of two). Three-phase motors deliver power at a steady and constant rate.
