LEESON Brakemotors, Three Phase, Drip Proof, C Face Less Base


Leeson brake motors are used with conveyors, machine tools, speed reducers, door operators and hoists which require a quick stop. They offer braking as a safety measure when power is cut abruptly.

Working Mechanism

  • Brake motors use an electromagnetic field for powering and braking the motor.
  • They function by pushing a magnetic pole rotor through the applied current.
  • The poles of the stator (surrounding the rotor) apply force to turn the shaft.
  • When static AC or DC current is injected into the unit, the poles of the stator become static and stop the rotor.

Features

  • Leeson brake motors have a drive-end, C-face endshield for quick installation.
  • They come with a drip-proof enclosure to ensure protection from dust, water and air-borne contaminants.
  • These NEMA B / C units offer premium Class B / F insulation for temperature control.
  • The brakes of these models are fail-safe and spring-set, owing to dual voltage brake coils.
  • They feature durable steel frame construction for structural rigidity and Polyrex EM lubrication to resist oil & water leakage at temperatures up to 40 degrees Celsius.
  • These triple-phase units have a power-off manual release for user convenience in case of power failure. The load is automatically stopped when power is cut off.
  • They offer continuous duty operation at speeds up to 1800 rpm.
  • These motors produce torque up to 3 hp at 60Hz power supply.

Standards and Approvals

  • NEMA
  • UL
  • CSA

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 do Class B and F insulation mean?

These motors have Class B or F insulation for temperature control. Class B insulated motors can handle temperatures up to 130 degrees C and Class F motors can withstand a maximum temperature of 105 degrees C.

What is the purpose of a shaft in a motor?

A shaft is a cylindrical component extruding out from the housing and motor. It converts energy from the motor into end-use applications.
