Selecting the Right Motor for the Right Drive
Control Techniques' drive and motor combinations provide an
optimized system in terms of ratings, performance, 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' 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'
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
performance and value.
Example
using the NT motor family and Digitax ST servo drive family

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
performance and saves time.
For comprehensive information on Control Techniques' motor and drive solutions, refer to our website.

When a Unidrive M, Unidrive SP or Digitax ST servo drive is
connected to a SinCos or absolute encoder, it can recognize and
communicate with the motor to obtain the “electronic nameplate”
data. This motor data can then be used to automatically optimize
the drive settings. This feature simplifies commissioning and
maintenance, ensures consistent performance and saves time.

Order Code Information for 230/460 V 190 mm Frame
The Unimotor E3/U3 190 frame models are now supplied with an 58 mm long output shaft. If replacing an existing Unimotor fm
190 E2/U2 model which has a standard 80 mm long output shaft add the suffix -SREL to the order code.
80mm long output shaft order code example:

* Ratings shown require connector option "H"
∆t = 212 ˚F (100 ˚C) winding 104 ˚F (40 ˚C) maximum ambient
All data subject to ±10% tolerance
Stall torque, rated torque and power relate to maximum continuous operation tested in a 68 °F (20 °C) ambient at 12 kHz drive switching frequency\
Nidec has an ongoing process of development and reserves the right to change the specification without notice
All other figures relate to a 68 °F (20 °C) motor temperature; maximum intermittent winding temperature is 284 °F (140 °C)
