Coreless DC Motors

Ironless DC Motors

Coreless dc motors, also know as slotless, ironless, basket wound, or cup motors, offer numerous features and benefits that differentiate them from iron core or slotted dc motors relatives.

 

These include:

    • High Acceleration/Deceleration

     

    • High Efficiency

     

    • High Momentary or Pulse Torque Capability

     

    • Linear Speed vs. Voltage

     

    • Linear Torque vs. Current

     

    • Longer Life When Compared To Comparable Iron Core Motors

     

    • Low EMI/RFI

     

    • Low No-Load Current

     

    • Low Starting Voltages

     

    • Low Torque Ripple

     

    • No Armature Reaction

     

    • No Magnetic Side Loading On The Bearings Axially or Radially

     

    • Significantly Lower Inductance

     

    • Used Virtually Exclusively In Extremely Small Brush DC Motor

     

    • Very Small Rotor Inertia

     

    • Virtually No Risk Of Demagnetization

     

    • Zero Cogging

     

    • High Acceleration/Deceleration

     

  •  

    The GMP Series of Coreless DC Motors offer designers the option to use coreless dc motors in designs that formerly could not afford coreless motors due to the significantly more expensive options then available.

     

    These coreless dc motors are a lower cost ironless motor solution to applications such as disposable Medical Devices, Diaphragm pumps, and electric locks, to name a few.  Zero cogging coreless dc motors usually are the ideal solution to power consumption sensitive and electrical noise intolerant applications.  Their low inductance and lack of magnetic side loading of their bearings results in, all relevant factors the same or similar, to superior brush and bearing life to an iron core dc motor

    GMP offers coreless dc motors are offered in a variety of diameters, windings and body lengths.  Diameters range from the diminutive 4 mm to a very robust 62 mm diameter motor, with continuous output powers of some in excess of 300 Watts.

     

    Options include 3 channel optical encoders, high torque planetary and quiet running spur gearboxes.  Both precious metal and graphite commutation is offered.  Custom assemblies and actuators utilizing them are also within our capability.
