Working Mechanism
- Farm duty AC motors work on the principle of magnetism as they contain two fixed magnets and a coil of wire surrounding a shaft.
- When an electric charge is applied to the coil of wire, it becomes an electromagnet, hence generating a magnetic field.
- The equipped stator includes a loop of wire, solid metal axle, coil, squirrel cage made of metal bars and some other freely rotating metal parts that are capable of conducting electricity.
- In an AC motor, sending power to the outer coils that make up the stator & the coils energise in sequence & pairs, generating a magnetic field that rotates around the motor.
Features
- Marathon farm duty / agriculture motors are supplied with thru bolts for quick and secure fastening.
- These high torque motors are single-phase units delivering torque up to 1 hp.
- They have a TEFC enclosure to keep motor windings clean, cool and dry.
- These units have an auger drive option, providing maximum speed and positional & dynamic accuracy.
- They feature rolled steel construction for structural rigidity and ball bearings to reduce motor friction.
- These products produce torque up to 1.5 hp on a 50 Hz / 60 Hz power supply delivering speeds up to 1800 rpm.
- They are available in Class B and F insulation types to withstand temperatures up to 40 degrees Celsius.
Frequently Asked Questions
What is the difference between single, double and triple-phase motors?
- 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.
What does continuous duty operation mean?
A continuous load is where the highest current is expected to operate continuously for three hours or more.
What is the difference between TEBC and TEFC motors?
Totally enclosed blower-cooled (TEBC) motors are virtually identical to TEFC motors with the exception that the motor body is cooled by a separate "blower" positioned on the body rather than by a shaft-mounted fan while the motor is working at a high speed.
