Performance AC Brushless Servo Motor

Overview
Unimotor FM is a high performance brushless AC servo motor range matched for use with Control Techniques drives. FM is an acronym for Flexible Motor, designed to accommodate a wide range of applications. The motors are available in six frame sizes with various mounting arrangements and motor lengths.

Applications
Unimotor FM is suitable for applications where precision motion and/or dynamic control is required. Typical applications include:

• High speed machinery
• Flying shear and rotary knife applications
• Pick and place
• Materials handling
• Printing
• Textile machinery

Benefits

•    High peak torque values allow smaller motors to be used where the RMS value is low but the maximum torque is high
•     A wide selection of ready made cables are available for quick and easy connection to Control Techniques drives
•     High inertia versions are available to allow the motor inertia to be more closely matched to the load inertia for increased performance and stability.
•     IP65 environmental protection is standard and ATEX protection available as an option.
•     Motor brakes may be integrated within the motor, a choice of parking brake or high energy dissipation brake is available.
•     Flexibility of the Unimotor range always ensure the best fit for your application, as well as the various physical sizes and feedback devices available,   options extend to the type of connectors fitted

Performance AC Brushless Servo Motor

 Unimotor FM is a range of brushless AC servo motors which support a winding to suit 200/240V or 400/480V nominal AC drives such as the , Unidrive classic, M’Ax and MultiAx range of drives. The range is available in six frame sizes 055:075:095:115:142 and 190mm, each frame size has a number of shaft diameter options and can offer various front flange mounting arrangements.
The 190 frame motor has been increased in variants from 4 (A-D) to 8 (A-H). The design also conforms to the sealing standard IP65 (when mounted and connected).

 Standard Features

• Modular rotor design.
• Rotor assembly balanced to ISO1940 ( BS 6861 ) G 6.3.
• Incremental encoder for high precision feedback.
• PTC thermistors for thermal monitoring and overload protection.
• IP65 standard; sealed against water spray and dust. (IP65 mating connectors must be used)
• Vertical connectors for power and signal. New Feature
• Low inertia is standard for fast acceleration.
• UL and cUL recognized motors (075-190 frame motors only).
• IEC mounting flange.
• Shaft key as standard.

 Optional Features

• A range of shaft diameter. New Feature
• Fixing hole dimensions (See PCD options on page 8-9). New Feature
• High inertia. * Other Incremental encoder interfaces available.
• Resolver feedback for rugged applications.
• Sin/Cos encoder for high resolution and accuracy (single and multi-turn). Other interfaces available.
• SLM technology. (075-190 frame motors only).
• NEMA mounting available.
• ATEX motors available (special conditions apply). (075-190 frame motors only).
• Plain shaft (non keyed).
• Electronic name plating (Available on Sincos motors only). (075-190 frame motors only). New Feature

Motor Specification

 Machinery Directive 89/392/EEC amended to 98/37/EC Low Voltage Directive 73/23/EEC

 Standard equipment is not deemed suitable for use in an explosive atmosphere. (ATEX motors are available, please contact your Drive Centre or Distributor for details). This product has been designed to be operated with Control Techniques Servo drives and must not be put into service unless the machinery into which it is to be incorporated has been declared in conformity with the provisions of the machinery directive.

Brake Specification

• The brakes are intended for parking duty and are not for dynamic or safety use.
• The brake will engage when power is removed.
• Refer to your Drive Centre or Distributor if your application requires dynamic braking in emergency conditions.
• To provide protection to the brake control circuit it is recommended that a diode is connected across the output
     terminals of the solid state or relay contacts devices.
• Larger torque brakes are available as an option. Please contact your Drive Centre or Distributor for details.
• Figures are shown at 20°C brake temperature. Apply the de rate factor of 0.7 if motor temperature is above 100°C.

 *Note 1 kgcm2 = 1x10-4kgm2 **Backlash figure will increase with time
