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.
