10. TRACTION MOTOR KEY TECHNOLOGIES
WINDING VS COOLING
The temperature is critical for both wheel-hub and geared high
speed drives. So thermal resistance between winding and
housing is important.
The continuous power is depended on the thermal resistance
from the winding to the cooling
Distributed winding
Concentrated winding
Insert winding Hairpin winding

11. TRACTION MOTOR KEY TECHNOLOGIES
WINDING VS COOLING
%25-30 more
power with hairpin
winding technology
or
Decreased winding
temperature with
higher efficiency

12. TRACTION MOTOR KEY TECHNOLOGIES
COOLING METHOD
Forced air cooling Water cooling Oil cooling
Wheel-hub motors are cooled with
air forced by the car’s
aerodynamic. This type of DD
motor has sufficient surface are
for forced air cooling.
Axial or radial pipe system are
used in stator housing for water
cooling
Axial or radial pipe system can
be used with oil and oil can be
sprayed over stator and rotor
inside the motor.
