Stappen motor NEMA34, 3,1Nm

Stappen motor NEMA34, 3,1Nm, 5,6Arms, 63mm; Model M1343011.



Stappen motor NEMA34, 3,1Nm, 5,6Arms, 63mm; Model M1343011.

The family of NEMA34 stepper motors spread over six different stator lengths.

The maximum torque exceeds 12Nm (1416oz-In) placing this series of stepper motors among the best performing commercially available.

All the motors have 8 wires and can be used both in bipolar and unipolar mode.

When the motors are used in bipolar mode (recommended to obtain the best performance) it is possible to choose between a series type connection, to limit the phase current, or parallel type, for applications exploiting the motors at high speeds.

The 14mm shaft diameter ensures stability in applications with belt transmission. Upon request the motor can be realized with 12mm shaft with key, with double shaft, etc.
