①
: When the motor is air-cooled and the torque is less than
T
c
, it can run continuously below
ω
n
without
break.

②
: When the motor is water-cooled and the torque is less than
T
cw
, it can run continuously below
ω
n
without break.
③
: When the motor is air-cooled and the torque is less than
T
c
or when it is water−cooled and the torque is
less than
T
cw
, the speed is greater than
ω
n
, the duty cycle must be reduced or additional design on rotor heat
dissipation must be provided to avoid overheating of the rotor.
④
: When the motor is air-cooled and the torque is greater than
T
c
or when it is water-cooled and the torque is
greater than
T
cw
, the duty cycle must be reduced. When
T
p
is reached, only 1 second output is allowed to avoid
overheating of the stator.

T-N Curve (IM-2)
The T-N curve is defined as the comparison chart of the torque and the speed that can be output under a certain
input voltage of the motor. Considering the temperature rise of the motor, the figure can be divided into two
operating ranges as shown on next page:
⑤
: When the motor is water-cooled and the torque is less than
T
cw
, it can run continuously below maximum
speed in field weakening without break.
⑥
: When it is water-cooled and the torque is greater than
T
cw
, the duty cycle must be reduced. When
T
p
is
reached, only 1 second output is allowed to avoid overheating of the stator.

Maximum input voltage (
V
DC
)
Maximum input voltage is the maximum voltage for the motor operating in the normal environment.

Maximum continuous power loss:
P
c
(
W
)
Maximum continuous power loss is the energy lost when the motor runs continuously under continuous
current and the coil temperature is 120
℃
(130
℃
for
□
M-2). It mainly converts into heat. In water cooling
system, the loss is mostly eliminated by coolant.

Maximum pressure difference:
∆ p
(
bar
)
Maximum pressure difference is the maximum value tolerated by the pressure difference between inlet and
outlet under water cooling system with pure water. It corresponds to minimum water flow q. If the operating
environment is different, pressure difference must be modified by calculation (refer to Section 3.6).
