LEESON 50 Hertz Motors, Single Phase, TEFC, Rigid Base
Leeson 50 Hz motors are single-phase units ideal for medium-to-high torque requirements in conveyor, auger drive, ventilation, shop tool and pump applications. They utilise a capacitor to offer extra power during startup for maximum torque.

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
- Leeson 50 Hz motors are equipped with a TEFC enclosure to permit the cooling air to flow through the motor, thereby preventing overheating.
- These single-phase models offer clockwise or counterclockwise rotational shafts with a keyed design.
- They come with high-quality ball bearings to deliver speeds up to 2875 rpm and a rigid base for easy mounting.
- These units are designed to produce torque up to 5 hp on a 50 Hz power supply.
- They are available in Class B and F insulation types to withstand temperatures up to 40 degrees C.
Frequently Asked Questions
Do these motors prevent overloads?
Yes, these Leeson motors have a manual reset thermal protector to prevent overloads.
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 class B and F insulation mean?
These motors have Class B or F insulation for temperature control. The Class B insulated motors can handle temperatures up to 130 degrees C and Class F can withstand a maximum temperature of 105 degrees C.
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.
