BRUSH HMA AND TRACTION MOTORS
MOTOR DESIGNS
BRUSH HMA has many years valuable experience with
the design and manufacture of traction motors for trains,
metro’s, trams and busses. This experience has been
built up over the years as the major motor supplier to
the Dutch Railways and local transport (tram and metro)
companies.
BRUSH HMA’s AC traction motors are specially designed
to suit customer’s requirements. Our experience has led
to a wide range of modular designs that can be adapted
to suit any particular application – bogie, axle or carriage
mounted, as well as water-cooled wheel hub motors are
available. Our motors are suitable for GTO- and IGBTswitched inverters of any make.
Until the end of the 1980’s, these motors were of DC
design, for use with chopper drives. With the fast
development of GTO and IGBT technologies throughout
the 1980’s and 1990’s, HMA’s specialist knowledge was
concentrated on the design of AC traction motors for
inverter drives, in close collaboration with the traction
department of the former Holec Machines and
Apparatus, now known as Alstom Traxis.
This collaboration has led to a wealth of experience
in the field of inverter driven motors under demanding
traction conditions.
Attention has been paid to designing rugged motors with:
•t low noise levels
•t low maintenance requirements
•t very high reliability
•t expected service lifetimes of over 30 years
HMA will design the performance of the motor to the
customers specification, ensuring an optimised solution
for the performance required and the bogie employed.
HMA also has the in house skills and specialised software
to carry out complicated dynamic drive line calculations to
predict the system’s dynamic performance.
