LEESON 50 Hertz Motors, Single Phase, TEFC, C Face Less Base

Leeson C-Face less-base 50 Hz motors are single-phase units utilising a capacitor to offer extra power during startup for maximum torque. They are ideal for medium-to-high torque requirements in conveyor, auger drive, ventilation, shop tool and pump applications.

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 produce torque up to 2 hp on a 50 Hz power supply.
  • These energy-saving motors feature durable rolled steel frame construction for structural rigidity and less-base C-Face mounting for ease of installation.
  • They are equipped with a TEFC enclosure to permit the cooling air to flow through the motor, thereby preventing overheating.
  • These units include easy-to-read nameplates for quick identification and high-quality ball bearings to deliver speeds up to 2850 rpm.
  • They are available in Class B and F insulation types to withstand temperatures up to 40 degrees C.

Standards and Approvals

  • CSA
  • UL
  • IEC IP54
  • NEMA

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.

Do these motors prevent overloads?

Yes, these Leeson motors have a manual reset thermal protector to prevent overloads.

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.

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.
