Series: SM, Frame Magnet Length: 232 mm. Winding: Type A, Feedback: 1000 ppr Encoder. Shafting: Flat. Connection: Tap Drive. Options: None. Parker Compumotor SM23AE-FTQN SM Series Brushless Servo Motor, Flat, Tap Drive - The SM Series brushless servo motors feature a slotless stator design. This design eliminates all detent torque in the motor, allowing the SM Series motors to provide extremely smooth motion, especially at low speeds. The slotless design also creates a higher rotor inertia, which is ideal for applications involving high inertial loads (such as lead screws and belt drives). The SM Series motors also feature a rugged anodized aluminum body and connector housing. An IP65 rating can be obtained on motors with MS connectors and an optional shaft seal. All SM motors are CE (LVD) compliant. The SM Series servo motors are available with integrated planetary gearheads in ratios up to 100:1. Our unique package integrates the gearhead pinion into the motor shaft, reducing the overall package length by up to 2 inches.. Parker. Parker. SM23AE-FTQN.
