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 automotive duty motors are supplied with a rigid base for ease of installation.
  • These three-phase units come with an oversized, fully gasketed terminal box for efficient operation in harsh environments.
  • They feature cast iron frame construction to ensure ultra-rugged performance.
  • These units deliver continuous duty operation at speeds up to 3600 rpm.
  • They are equipped with a TEFC enclosure to permit cool air to flow through the motor, thereby preventing overheating.
  • These Class F insulated units produce torque up to 3 hp at 60Hz power supply.

Standards and Approvals

  • CSA
  • UL
  • NEMA

Frequently Asked Questions

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.

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 does Class F insulation mean?

These motors have Class F insulation for temperature control. Class F insulated motors can withstand a maximum temperature of 105 degrees Celsius.
