Brushless DC Motors

Built for precision, efficiency and reliability,
these motors offer the power density
needed to deliver top performance in the
most compact applications. Available in
slotted and slotless designs, they provide
exceptional acceleration, speed, torque

and position control over a long, trouble-
free life.

Exceptionally Efficient, Powerful and Durable

Feature Details Application Advantages
• Zero detent torque
• Reduced iron losses
• Slotless: self-supporting cylindrical coil
• High efficiency
• Linear torque vs. speed
Slotless or slotted configurations
• Excellent torque-to-power ratio
• High current capability
• Slotted: coils inserted in the slots of the stator
• Withstands rugged environments
• Autoclavable option
• Linear torque/speed curve (except iron losses)
Permanent magnet • Torque proportional to current • Ease of position and speed control
• Speed proportional to voltage
• Long life, limited only by ball bearing wear
• Electronic commutation • Reliable in harsh and dusty environments
Brushless design
• No brushes to wear or spark • Reduced EMI
• Quiet operation
Winding attached to stator • Improved heat dissipation via conduction • Superior overload capacity
• Motor design optimized to withstand exposure to
Autoclavable versions for slotted motors harsh environments including high temperature • Long life in medical devices that
and pressure cycling undergo frequent sterilization
