Servo Drives and Servo Motors
Unimotor is a comprehensive family of high performance AC brushless servo motors. With a wide torque range, from 0.72 Nm up to 136 Nm, rated speeds from 1000 rpm to 6000 rpm, several inertia levels and a broad selection of feedback options, Unimotor offers the perfect fit for any application requirement. Various mounting arrangements and a single cable option provide additional flexibility, while drive integration with electronic nameplate offers ultimate ease of use.
To optimize performance, we segment our servo drives and motors by the duty required for the application.
- Pulse Duty - High dynamic applications requiring hard accelerations and decelerations. Examples are pick-and-place, flying shear and other cut-to-length machines. These applications are characterized by high peak (e.g. 300% overload) and moderate RMS torque.
- Continuous Duty - High-precision over an extended duration requiring lower acceleration and deceleration rates. Examples include printing, winding and labelling. These applications are characterized by moderate peak and high RMS torque.

Digitax ST is a dedicated servo drive optimized for pulse duty. The servo drive is available in five variants, and is designed to meet the demands of modern manufacturers for smaller, more flexible and higher performing machinery.
0.75 kW – 2.8 MW (1.0 – 4,200 hp)
200 V / 400 V / 575 V / 690 V
Unidrive M700 provides high performance motor control and ultimate control flexibility in order to satisfy the requirements of machine builders and high specification industrial applications. Unidrive M700 offers an enhanced upgrade for existing Unidrive SP users.
2.2 – 16.0 A rms (4.4 – 32 Peak)
115V / 230V
Epsilon EP, Control Techniques’ compact and easy-to-use servo drive, is scalable from a simple amplifier to a completely programmable 1.5-axis motion controller.
The Epsilon EP is available in three flexible models – Epsilon EP-B (base), Epsilon EP-I (indexer), and Epsilon EP-P (programming).
Each model is available with five drive different power stages—2.2A, 4.0A, 6.5A, 9.0A and 16.0A—providing the capability to deliver over 198 lb-in (22.4 Nm) of torque at the rated motor speed and 396 lb-in (44.8 Nm) of peak torque for those high demanding pulse duty application.
AC Servo Motors
Unimotor is Control Techniques’ high dynamic brushless AC servo motor range, designed for operation with Unidrive M, Digitax ST, Unidrive SP and Epsilon EP drives.
Unimotor hd is a high peak torque, low inertia motor range. Designed for high dynamic applications requiring hard accelerations and decelerations.
Unimotor fm provides high-precision over an extended duration requiring lower acceleration and deceleration rates. The motor is optimized for high stability in precision profiling applications.

Unidrive SP can control a wide range of industrial motors. In Servo mode the drive operates as a high performance servo amplifier, matched to the Unimotor fm motor range and optimized for continuous duty applications due to its high continuous output rating. Typical continuous duty applications are printing, winding and labeling.
