LEESON Brakemotors, Three Phase, TEFC, C Face With Base
Leeson brake motors are used on 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 feature durable steel frame construction for structural rigidity and Polyrex EM lubrication to resist oil & water leakage at temperatures up to 40 degrees Celsius.
- They have a drive-end, C-Face endshield with rigid base mounting for quick installation.
- These NEMA Design B 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.
- These motors produce torque up to 10 hp at 50 / 60Hz power supply.
- They come with a TEFC / TENV enclosure to ensure protection from dust, water and air-borne contaminants.
- These triple-phase units have a power Off manual release for user convenience in case of a power failure. The load is automatically stopped when power is turned Off.
- They offer continuous duty operation at speeds up to 1800 rpm.
Standards and Approvals
- NEMA
- IEC
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 difference between TENV and TEFC motors?
Totally enclosed non-ventilated (TENV) motors are designed without air openings and are ideal for applications where frequent sanitising or cleaning is required. TEFC (totally enclosed fan-cooled) motors come with an external fan to circulate outside air to the motor.
