Example n°3 :
This time, the application needs :
- a rms torque of
4500 Nm at the rms speed of 100 rpm ,
- an acceleration torque of 5000 Nm ,
- a maximal speed of 120 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 I0 of the motor is 126 Arms for 4720Nm at low speed.
The nominal current In of the motor is 126 Arms for 4720 Nm at the nominal speed.
Selection of the drive:
The datasheet shows a torque sensitivity of 37.5 Nm/Arms. This means that the drive
has to provide at least 4500/37.5=106 Arms.
In order to obtain an acceleration torque of
5000 Nm , the current will be of about 133
Arms
(the motor data sheet shows 5190 Nm with 139 Arms). This means that the drive has
to provide at least 133 Arms as transient current.

Therefore, we can select the drive AC890 PARKERSD-43 3105 F which delivers
under 400Vac:
126 Arms as permanent current and
126*110%=138 Arms as maximal transient current during 60 s.
Under these conditions, the drive must run with
“Quadratic as Servo Mode”.
The example n°3 illustrates the situation where the motor observes a “derating” mode
due to the current limitation set by the drive.
- the permanent torque authorized will be equal to 4720 Nm,
- the maximal transient torque will be equal to 5185 Nm during 60 s.
