MARATHON MOTORS 5KC49PN0155 Motor 1/2 Hp 1725 Rpm 115/208-230v None

Marathon 5KC49PN0155 motor is used in band saws, drill presses, ventilators, farm equipment and summer cooling fans. It converts AC power into torque to drive mechanical loads. This torque is the measure of twisting or rotational force.

Features:

• Marathon 5KC49PN0155 motor has permanently lubricated, double sealed ball bearings for a smooth movement, extended motor life and reduced motor friction.
• It features an open drip-proof enclosure to permit external airflow through the motor windings to keep it cool during continuous operation.
• This Class B insulated unit offers a single-phase design and attain a maximum speed of 1800 rpm.
• It allows cradle base mounting with either horizontal / vertical orientation for user convenience.
• The model comes equipped with resilient ring mounts to keep the motor suspended for reduced vibration and noise produced during motor startup.
• This steel-constructed motor has a keyed shaft with clockwise / counterclockwise rotation.

Standards and Approvals:

• CSA
• UL

Frequently Asked Questions:

Q. What is the difference between single, double and triple phase motors?

A.

• Single-phase motor: Current flows through a single conductor.
• Double-phase motor: Current flows through 4-wire conductors (2 for each phase).
• Triple-phase motor: Current flows through 3 separate conductors.

Q. What is the purpose of a keyed shaft?

A. A shaft key is a piece of metal that connects a rotating machine element to the shaft. It enables torque transmission and prevents relative rotation between two parts.

Q. What does Class B insulation mean?

A. The motors have Class B insulation for temperature control. The Class B insulated motors can handle temperatures up to 130 degrees Celsius.
