Features
- These motors come with a totally enclosed fan-cooled enclosure for completely sealing outside air to circulate within the motor. They have an external fan attached to the enclosure to cool the motor down.
- They feature bolt-on-base mounting for quick removal / installation.
- These units eliminate the need for a capacitor, start winding, centrifugal switch or other starting devices that can wear out or fail in high starting torque conditions.
Frequently Asked Questions
Are these 3-phase brake motors AC or DC?
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.
Where are three-phase braking motors used?
Marathon three-phase braking motors are used in crushers, cranes & hoists, plungers and conveyors.
Is a three-phase motor more powerful than a one-phase motor?
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.
