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.

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.
