MICROSPEED
The transformer's nominal power is calculated based upon
the sum of power from the single motors driven.
Or Better:
Note: In multi-axis applications, the transformer's power can
be downgraded by 30%.
•••••
POWER:
If the power of a transformer exceeds a
determined value, the inserted straightening point
could be damaged in the enabling phase, due to
overcurrent from the capacitors.
•
max. power per trasformer is 7KVA;
Where:
Pn Motor
= nominal power each motor.
n
= max. speed of motor in RPM.
Cn
= nominal torque of motor in (Nm).
Pn Motor =
n
x Cn

C (uF) = P (VA) transformer x 1000

Power Transformer:
Capacitor filter:
In regards to the capacitor filter we suggest a working voltage
of:
--100 Vdc for Microspeed plus 60
--200 Vdc for Microspeed plus 140
--300 Vdc for Microspeed plus 200
It's capacitor value is derived using the following formula:
P(VA)=Power absorbed motor 1+Power
absorbed etc......
