Working Mechanism
- Electric motors convert electrical energy into mechanical energy for generating motion.
- Force is produced within the motor through the interaction between a winding alternating (AC) or direct (DC) current and the magnetic field.
Features
- Marathon general-purpose motors have 3-phase operation to deliver constant power and provide vibration-free & smooth performance at speeds up to 1725 rpm.
- They can be installed at any angle for user convenience.
- These units feature steel or rolled steel construction with a keyed shaft having clockwise / counterclockwise rotation.
- Open drip-proof enclosures allow air to flow through the motor and prevent overheating.
- They have squirrel cage induction for constant speed.
- The ball bearings are mechanically locked on the shaft end to reduce motor friction.
- These models are available in Z, H and C-frame types.
Frequently Asked Questions
What is the difference between single, double and triple-phase motors?
- Single-phase motor: Electricity flows through a single conductor.
- Double-phase motor: Electricity flows through 4-wire conductors (2 for each phase).
- Triple-phase motor: Electricity flows through 3 separate conductors.
What is the purpose of a keyed shaft?
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 the two parts.
What does Z, H and C frame construction indicate?
- Z: The frame has a non-standard shaft.
- H: The frame has a set of mounting holes at 3 & 5 inches.
- C: The motor can be face-mounted.
- These letter designations and frame standards are defined by NEMA
