MDM-5000 Direct Drive Sets (Frameless Motors Kit) for Frameless Servo Applications)

MDM-5000 Direct Drive Sets (Frameless Motors Kit) have been developed to fit applications where size and weight are important factors. Direct Drive technology allows for high servo stiffness which maximizes rate and position accuracy because there are no belts, gears or backlash inherent with most other servo systems. MDM-5000 Direct Drive Sets are supplied as two pieces; a cut-core segmented stator and a rotor. The stator is molded in a thin walled aluminum housing using thermally conductive epoxy, which provides excellent heat transfer and protects the windings (and optional integrated Hall board) from damage during installation and handling. The rotor is coated with a polymer shrink wrap which protects the magnets from dislodging during operation and also prevents damage while handling.

Technical Specifications

  • Brushless design provides high performance with zero maintenance
  • Cut-core or Segmented Stator Technology means high efficiency, high slot-fill windings Stator molded in thin wall aluminum housing using thermally conductive epoxy provides excellent heat transfer, high torque density and protects the windings and optional Hall board from damage
  • Rotor coated with polymer shrink wrap which protects magnets from dislodging during operation and prevents accidental damage while handling
  • High pole count, low cogging, smooth operation
  • High torque to inertia ratio ideal for high acceleration/deceleration mode with rapid start-stop
  • Low electrical time constant for fast response
