Example :
The application needs:
- a rms torque of
6 Nm
at the rms speed of 4000 rpm,
- an acceleration torque of
25 Nm
,
- a maximal speed of 4500 rpm.
Selection of motor:
The selected motor is the type
EY630EAK
.
The nominal speed is equals to 4800 rpm.
The maximal speed is equals to 4800 rpm.
The torque sensitivity is equals to 1.17 Nm/Arms.
The permanent current
I
0
of the motor is
10.3 Arms
for
M
0
=12 Nm
at low speed.
The nominal current
I
n
of the motor is
5.56 Arms
for
M
n
= 6.25 Nm
at the nominal speed.
Selection of the drive:
The drive has to provide at least a permanent current equals to I
0
(10.3 Arms). In order
to obtain an acceleration torque of
25 Nm
, the current will be about 25/1.17=22 Arms.
This means that the drive has to provide at least 22 Arms as transient current.
Therefore, we can select the drive
AC30
31V-4D0012 which delivers under 400 VAC:
12 Arms
as permanent current and about,
12
*
200%
=24 Arms as maximal transient current during 4 s.
The drive is set with
“Servo Mode”
.
