Main performance characteristics
In most cases, PMSMs are made with salient poles. Their performance is judged by the following performance characteristics:
- cos φ – power factor, which is equal to the cosine of the phase shift of the alternating current relative to the voltage applied to it;
- M – torque;
- η – efficiency factor;
- n – rotation frequency.
Taking into account the ability of electric motors to operate with leading cos φ when overexcited, they are manufactured for nominal operation at cos φ = 1 and leading cos φ = 0.8. The frequency of the rotating shaft is constant in all modes:
n = 60*f1/p,
where f1 is the frequency of the stator current;
p –
number of pole pairs of the stator winding.
The torque is equal to:
M = M0 + M2,
where M0 is the idle torque and is a constant value;
M2 – useful torque changes in proportion to useful power and is equal to:
M2 = P2/
