Drive and Motor Selection

Emerson Industrial Automation drive and motor combinations
provide an optimized system in terms of ratings, perbance,
cost and ease of use. You can manually select the system
components using the following steps, or download the
SERVOSoft ® sizing software which includes our Control
Techniques' brand of servo drive and motor data.
1. Determine the application’s continuous and peak torque
requirements at various motor shaft speeds, then refer to
motor data tables and the visual reference overview to help
determine which motor family will be most appropriate for
the application.
2. Once the motor family is selected, use this brochure to select
a specific motor model that delivers the required torque and
speed. Make note of the continuous and peak current (Amps)
requirements of the selected motor.
3. Check the specification tables in the Control Techniques'
brand individual drive brochures for Digitax ST, Epsilon EP,
Unidrive M or MDS servo drives to select the drive model
that delivers adequate continuous and peak torque for the
selected motor.
4. Refer to the Servo Motor Cables section of this brochure to
select the motor power and feedback cables for the selected
motor and drive.
5. Confirm that the ratio of rotor inertia to load inertia is <10:1
load inertia/rotor inertia <10
Note: A gear reducer will reduce the load inertia based on the
following equation:
Reflected load inertia = load inertia/gear ratio 2
Note: When specifying a motor system, be sure to consider
such options as user-interfaces (HMI), braking resistors and
other options and accessories that will enhance the system’s
perbance and value.
Electronic Nameplates
Some motors fitted with high-resolution SinCos or absolute
encoders are pre-loaded with the motor “electronic nameplate”
data during the manufacturing process. This data can be read
by most Control Techniques' brand servo drives and used to
automatically optimize the drive settings. This feature simplifies
commissioning and maintenance, ensures consistent perbance
and saves time.
