MDrive® 23 Linear Actuator with AccuStep
MDrive 23 Step Motor Linear Actuators feature high torque NEMA 23 (2.3"/56mm sq.) 1.8° brushless linear actuators integrated with electronics. A broad input voltage range from +12 up to +75 VDC and an extended operating range of –40° to +85°C provide long life, trouble free service in demanding environments.
AccuStep – revolutionary motion control technology
that prevents loss of synchronization (unintentional
stalling) due to transient or continued overload, extreme
acceleration or deceleration, or excessive slew
speed – is available in two linear motion versions:
- Step • Torque • Speed, three operating modes
all-in-one motor + driver + encoder + AccuStep - Motion Control, fully programmable
motor + driver + controller + encoder + AccuStep
