Working Mechanism
- The brake motors use an electromagnetic field for powering the motor and braking.
- They function by pushing a magnetic pole rotor through the applied current.
- Surrounding the rotor, the poles of the stator apply the force to turn the shaft.
- When static AC or DC is injected into the unit, the poles of the stator become static and stop the rotor.
Features
- Leeson general purpose DC motors are equipped with a TEFC enclosure to keep motor windings clean, cool and dry.
- They come with a C-Face and removable base for convenient installation.
- These motors produce torque up to 3 hp and continuous duty operation with speeds up to 2500 rpm.
- They are available in Class B and F insulation types to withstand temperatures up to 40 degrees Celsius.
- These units are supplied with DC controls to change the speed of the motor.
- They are equipped with ball bearings to handle heavy axial and radial loads.
- These units offer clockwise or counterclockwise rotating shafts with a keyed design.
- The supplied carbon constructed, oversized brushes ensure long life and are easily accessible.
Frequently Asked Questions
What does continuous duty operation mean?
A continuous load is where the highest current is expected to operate continuously for three hours or more.
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.
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 while the motor is working at a high speed.
What do you mean by Class B and F insulations?
These motors have Class B or F insulation for temperature control. The Class B insulated motors can handle temperatures up to 130 degrees C and Class F can withstand a maximum temperature of 105 degrees C.
