Peak voltage on motor

When a transistor in the inverter is opened,

the voltage across the motor increases by a

dV/dt ratio that depends on:

the motor cable (type, cross-section, length

shielded/armored or unshielded/unarmored)

inductance

The natural induction causes an overshot U

PEAK

in the

motor voltage before it stabilises itself at a level which

depends on the voltage in the intermediate circuit.

The rise time and the peak voltage U

PEAK

affect the

service life of the motor. If the peak voltage is too high,

motors without phase coil insulation are the ones that

will primarily be affected. If the motor cable is short (a

few feet), the rise time and peak voltage are lower.

If the motor cable is long (333 feet), the rise time

and peak voltage will increase.

If very small motors are used without phase

coil insulation, it is recommended to fit a LC

filter after the AFD.

Typical values for the rise time and peak voltage U

PEAK

measured on the motor terminals between two phases:
