Features
- Marathon Motors offers general-purpose AC motors with power ratings ranging from 0.75 to 500 HP.
- The brand's HVAC motors have open dripproof enclosures and can rotate both clockwise and counter-clockwise directions.
- Marathon general-purpose AC motors feature continuous duty and can handle fluids up to 40 degrees C.
- The brand's jet pump AC motors have double-sealed ball bearings and a mechanically locked on shaft end for smooth high-pressure operations.
Working Mechanism
- AC motors function through the principles of electromagnetism.
- Alternating current is supplied from an external source to energise coils of wire arranged within the stator.
- As the current alternates direction, it produces a rotating magnetic field within the stator.
- This rotating magnetic field induces a voltage in conductive elements housed in the rotor, generating current.
- These induced currents create their own magnetic fields, which interact with the stator's rotating magnetic field.
- The resulting electromagnetic forces exert torque on the rotor, causing it to rotate.
Frequently Asked Questions
What are the differences between ODP, TEFC and TENV motor enclosures?
- ODP motors have openings in the enclosure for air circulation and cooling, but they are susceptible to dust and moisture ingress.
- TEFC motors are enclosed to keep dust and moisture out, and an external fan cools them.
- TENV motors are fully enclosed and sealed to prevent contamination, making them suitable for harsh environments. But, they require alternative cooling methods, such as heat dissipation through the enclosure walls.
What are the differences between single-phase and three-phase general-purpose AC motors?
- Single-phase general-purpose motors operate using a single alternating current phase and are commonly used in light commercial applications. They have lower power ratings and efficiency compared to three-phase motors.
- Three-phase general-purpose motors, on the other hand, use three alternating current phases and are preferred for industrial and heavy commercial applications due to their higher power output.
How can we keep Marathon AC motors from malfunctioning or failing prematurely?
- To avoid malfunction or breakdown:
- Install or mount the motor properly.
- Give the motor adequate ventilation to avoid overheating.
- Check regularly for excessive vibration or misalignment.
- Protect the general-purpose motor from dust, dirt or moisture.
- Do not overload or underload the AC motor beyond its specifications.
How do I choose between a general-purpose AC motor and a DC motor?
General-purpose AC motors operate on alternating current, while DC motors operate on direct current. AC motors are more cost-effective and easy to control in applications having adequate AC power. DC motors offer advantages, such as precise speed control, high starting torque and suitability for battery-powered or remote applications. The choice between AC and DC motors depends on the power source availability, speed & torque requirements, control complexity and cost considerations.
