NIDECUnimotor hd, Unimotor fm, NT Series and XV Series 0.9 - 1,204 lb-in (0.11 - 136 Nm) 230 V | 460 V Servo Motors

used to automatically optimize the drive settings. This feature 

simplifies commissioning and maintenance, ensures consistent 

performance and saves time

Example

using the NT motor family and Digitax ST servo drive family

Step 1: The application requires 12 lb-in continuous torque.

Step 2: The Servo Motors brochure lists the NT-212 motor 

with 2.7 A stall current.

Step 3: Select the Digitax ST drive with adequate current rating.

Flexible Configuration AC Servo Motors

Unimotor fm is a high performance, brushless AC Servo 

motor range matched for use with Control Techniques' brand 

drives. “FM” stands for “Flexible Motor” and is designed to 

accommodate a wide range of applications. The motors are 

available in six frame sizes with various mounting arrangements 

and motor lengths. Control Techniques' drives and motors are 

designed to function as an optimized system. Unimotor fm is the 

perfect partner for Unidrive M, Digitax ST and Epsilon EP servo 

drives.

NOW WITH EVEN HIGHER PERFORMANCE!

Electronic Nameplate Capability

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.
