Example n°1 :
The application needs:
- A rms torque of
4000 Nm at the rms speed of 100 rpm ,
- An acceleration torque of 7000 Nm ,
- A maximal speed of 140 rpm .
Selection of the motor:
The selected motor is the type
TMW306LR .
The nominal speed is equal to 125 rpm.
The maximal speed is equal to 155 rpm.
The torque sensitivity is equal to 37.5 Nm/Arms.
The permanent current I
0
of the motor is 130 Arms for 4870 Nm at low speed.
The nominal current I
n
of the motor is 129 Arms for 4800 Nm at the nominal speed.
Selection of the drive:
The drive has to provide at least a permanent current equal to I
0
(130 Arms).
In order to obtain an acceleration torque of 7000 Nm , the current will be about 190
Arms
(the motor data sheet shows 7200 Nm with 195 Arms). This means that the drive has
to provide at least 190 Arms as transient current.

Therefore, we can select the drive AC890 PARKERSD-43 3156 F which delivers
under 400 VAC:
135 Arms as permanent current and
135* 150%=202 Arms as maximal transient current during 60 s.
Under these conditions, the drive must run
with “
Constant
as Servo Mode”.
