Performance
and Reliability:
ELMECH: Cranes
are the result of 27 years of engineering expertise and qualitative
research. Designed and manufactured by qualified engineers to Indian
and International standard. ELMECH Cranes
come in a wide range to suit various applications.
ELMECH Brake
Motors: A Simple Principle.THE
PRINCIPLE:The
design concept of the combinations of electric motor and brake has been
solved by the brake motor with the tapped sliding rotor. This drive unit
was patent in 1924 as a crane drive “Where the brake is rigidly joined
to the tapped sliding rotor” since then this type of drive unit has proved
itself to be very reliable.The
sliding rotor brake motor known as the ELMECH brake
motor has a tapered rotor and stator pack. This creates a vertical and
horizontal magnetic field.The
former creates the torque as in every other electric motor and the latter
brings about an axial force which when switched on moves the rotor with
the firmly attached brake disk axially against the brake spring. This
release the brake. (Refer brake operation arrangement diagram on reverse.)When
the motor is switched off the magnetic field disappears and consequently
the axial force and the brake spring press the rotor with the brake disk
against the braking surface.
Advantages
- Simple and robust braking system.
- No additional switching components, rectifier
and solenoid coil required for the brake.
- Simultaneous operation between motor starting
and brake release and also between
- switching the motor off and application of brake.
- A Large number of starts per hour because starting
against a delayed brake release is
- impossible and the motor is not additionally
heated by a brake coil.
- High braking torques are possible due to the conical
brake design.
- Long life of the brake lining due to an efficient
heat dissipation from the braking surface and the flexible mounting of the lining on the
disk
- Simple replacement of brake lining.
- Drive unit suitable for the conversion to micro
speed unit simply by using brake as an automatic clutch.
- Brake disk incorporated an integral fan system,
thus shorter length.
- No additional connections for the braking system
the normal motor connections suffice
