  Dynetic Systems Coreless Motors

These small DC motors are sometimes referred to as “ironless” or “basket” motors. Their smooth operation, especially at high speeds, offers maximum power in a small package. Coupled with an encoder they make superior DC servo motors. These motors can be matched with gearheads offering increased torque and a wider range of speed control.

Standard features include:
• High efficiency • Low mass
• High speed capability • Rapid acceleration and deceleration
• Less cogging • Reduced torque ripple or cogging
• Low inertia • Smooth low speed operation
• Low mechanical time constant • True linear torque

Custom features include:
• Stainless Steel Case • Special connectors
• Low Backlash Gearheads • Planetary or Spur Gearing
• Precious Metal Commutation • Custom speeds and/or torque windings
• Custom bolt pattern • Custom front or rear shaft
