The Akribis ACR series ironless arc motors are designed for angular motion with constrained rotation up to 360 degrees.

Compared with DDR motors the ACR series arc motors feature larger centre holes, lower profile, and higher stiffness. 

When coupled with larger radius circular encoder scales and arc bearings, ACR motors can achieve better positioning, repeatability, and accuracy.

Features and Benefits:

• Ironless technology and no cogging force
• Thin coil design with low mass
• Large centre hole
• Integrated Hall sensor and temperature sensor
• Direct drive with high torque without cogging effect
• Limit-angle or 360-degree operation
• Flexible configuration with multiple coils or tracks
• Multiple coils connected in series or parallel to increase torque output
• Multiple tracks attaching together to extend angle of rotation
• High motor constant

Configurations:

ACR arcmotors allow customers to configure motors to suit their requirements:
For example, multiple coils can be used to increase torque output, or multiple tracks to increase range of motion.

Applications:

In applications with limited angle of rotation, direct drive rotary motors are not always necessary. ACR arc motors can provide a lower cost solution and save space, particularly in systems with large radius of motion. 

Compared with conventional direct drive rotary motors, ACR arc motors can provide a larger centre hole, lower profile, and high torque output. 

ACR arc motors aid the development of more compact systems which in turn are more competitive.

Akribis ACR series arc motors are applicable to G2.5, G4.5, G6, G8.5, G10.5 and G11 LCD, 8-inch or 12-inch wafer processing and inspection equipment, as well as biomedical devices, precision assembly and industrial printing machines.

Available sizes:

Direct Drive Technology
Direct drive technology eliminates the necessity for couplings, gearboxes and belts. It is well suited to high precision applications requiring dynamic precision both in speed and positioning.

Attributes include:

• Improvement in response and load control over traditional motor technologies.
• Improved cycle time
• Improved product quality.
• Cost effective solutions
• Fewer wearing components

Direct drive products are generally driven by standard servo drives such as the Kollmorgen AKD Gen I and Gen II ranges utilising linear or rotary encoders for feedback and precise positioning. Visit www.micromech.co.uk for a full range of complimentary products.

Markets
Direct drive technology is suited to all traditional markets utilising rotary and linear motion control.

The Akribis range of products includes:

• Linear motors
• Direct drive rotary motors
• Voice coil motors

Systems including custom system design for OEMs
