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 AC motors consist of auxiliary winding, main winding and a capacitor start.
  • They offer continuous duty operation with ball bearings to deliver speeds up to 1440 rpm.
  • These Class B insulated units feature steel construction for structural rigidity and a cradle base to ensure easy mounting.
  • They are equipped with an open drip-proof enclosure to permit the cooling air to flow through the motor, thus preventing overheating.
  • These single-phase models offer clockwise or counterclockwise rotational shafts with a keyed design.
  • They allow continuous duty operation and can withstand temperatures up to 40 degrees Celsius.

Standards and Approvals

  • CE
  • CSA
  • UL
  • 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.

How to choose between open and drip-proof enclosure motors?

Open enclosure motors are ideal for locations with minimum ventilation. Their open style design ensures that the air circulates freely through the motor. On the other hand, open drip-proof enclosures offer ventilation and prevent liquid drips from getting into the motor enclosure.

What does class B insulation mean?

These motors have Class B insulation for temperature control. The Class B insulated motors can handle temperatures up to 130 degrees C.
