3.3.1 Duty
Three-phase induction motors are usually designed to deliver their rated power in continuous service with no overheating
problems. However, most motors operate under a non-continuous type of service. Some motors are switched on for a few
moments only, others work all day, but they only charge up briefly, etc. The EN 60034-1 standard defines 10 main service types
and those summarised in the table below apply to MAC QM motors:
Duty
Description
Definition
S1
Continuous duty
Operation under constant load, for a time duration enough to reach
thermal balance.
S2
Short-time duty
Operation under constant load, for a time period shorter than required to
reach thermal balance, followed by a standby period that is sufficient to
cool down to ambient temperature.
S3
Intermittent periodic duty
A series of identical duty cycles consisting of a constant-load period
followed by a stillstand period.
S5
Temporary intermittent duty
with starting and electric
braking
A series of identical duty cycles consisting of a start period, a constant-
load period and an electric braking period, followed by a stillstand
period.
S6

3.3.5 Vibration grade
The EN 60034-14 international standard specifies the factory acceptance vibration test procedures and vibration limits for certain
electrical machines under specified conditions, when uncoupled from any load or prime mover.
The standard defines two vibration grades: Grade ‘A’ (machines with no special vibration requirements); and Grade ‘B’ (machines
with special vibration requirements).
The table below shows the limits of maximum vibration magnitude in displacement, velocity and acceleration (RMS) for shaft

3.3.6 Insulation class
The insulation thermal class rating of an electrical machine is identified on the motor nameplate by means of a letter in
accordance with the IEC/EN 60034-18 international standard. The table below summarises the maximum allowed temperature in
the insulation system of a winding in accordance with its insulation thermal class rating:
Thermal

3.3.7 Stress category severity
The table below describes the four stress categories defined in the IEC 6034-18-41 international standard:
Stress category
Overshoot Factor (OF)
Up/Ua
Impulse Risetime
A –Benign
OF ≤ 1,1
0,3 μs
B –Moderate
1,1 < OF ≤ 1,5
C –Severe
1,5 < OF ≤ 2,0
D –Extreme
2,0 < OF ≤ 2,5
Table 10: Phase-to-ground stress categories
3.3.8 Heating limits
The IEC60034-1 international standard defines the maximum admissible heating (temperature rise) for the windings as specified
in the table below:
Thermal class
Coolant
temperature
Heating
(per element)
Operating
temperature
B (130ºC)
< 40ºC
< 80ºC
< 120ºC
F (155ºC)
< 40ºC
< 105ºC
< 145ºC
H (180ºC)
< 40ºC
< 125ºC
< 165ºC
Table 11: Heating limits
In this regard the rated working conditions of the motor must be such that the operating temperature on the windings is always
below the temperature specified by the insulation class of its composing materials. Therefore, the working thermal class of a
motor can correspond to the following:
a) The same thermal insulation class. This would be the case of a motor built with Class F insulation (155°C) with a
maximum working temperature of 140°C, corresponding to a Class F.
b) A thermal class lower than the insulation class. This would be the case of a motor built with Class H insulation
(180°C) with a maximum working temperature of 140°C, corresponding to a Class F.

3.5.2 Ambient conditions
In their standard version, MAC QM motors are not suitable for working in saline or corrosive atmospheres or for installation
outdoors.
3.5.3 Duty
The rated power assigned for continuous service (S1 duty type) assumes an ambient temperature between -20º and +40ºC and
altitudes of up to 1000 m.
If the working conditions are different from those above, a derating factor (K1) must be applied to the rated torque and power
(See table below):

Table 14: Declassing factors
If the motor does not work in continuous service (S1), but rather in an S2 Short-time duty type, a multiplication factor must be
applied (K2) to the torque and power specified on the nameplate (S1 Service) to determine the torque available for this service.
The K2 factor is determined by the duration of the service according to the graph below.
