High Performance Slotless Brushless DC Servo Motors smooth, quiet motion. Low inductance and high current bandwidth provides precise control. Slotless outputs. AMETEK slotless brushless motors have no teeth to attract the magnets, cogging is eliminated, and the motor produces smooth, quiet rotation. The absence of teeth also provides room for larger and more wire in the windings, which means that slotless moters can generate more torque without a correslotted and slotless motors, eddy currents are induced as the magnets pass the stator. However, these currents are weaker in slottless motors, because the distance between the stack and the magnets is 0.3 oz-in. (0.002 Nm) 0.9 - 1.1 oz-in. (0.006 - 0.007 Nm) 1.8 - 4.3 oz-in.
