The 34HS1456 Nema 34 is a two-phase stepper motor that has a step angle of 1.8° (200 steps/rev). Each phase draws 5.6A at 3.08V, giving a holding torque of 8.4Nm. The motor has four color-coded wires: red and green represent one coil; yellow and blue represent the other. We use a bipolar stepper motor driver to control the 34HS1456 stepper motor.

Nema 34 step motor 5.6Nm and its advantages:

  • High torque
  • Smooth movement
  • High efficiency
  • Energy saving
  • Low noise level
  • Minimal vibrations
  • High torque
  • Low starting current
  • Reliability.

How to connect 34HS1456 Nema 34 stepper motor with driver?

As shown in the wiring diagram, there are four wires of different colors viz. red, green, yellow and blue. These wires are connected to two different coils. Red and green are connected to one coil and yellow and blue to the other. To rotate the motor, the coils are energized in a logical sequence.

How to control Nema 34 stepper motor?

The stepper motor is controlled via the stepper motor driver with pulse and direction signals. These signals are generated by the PLC, microcontrollers or pulse generators. If we need a stepper motor for a CNC machine, we do motion controller.

Other related components

34HS1456 stepper motor Nema 34 is compatible with DM860 drivers and 68V 300W unregulated power supply or 60V 350W switching power supply. We can also use DM2522 driver that connects to mains power, so we don't need an additional power supply.

Check it out too L bracket for fixing the Nema 34 stepper motor to the base and jaw couplings to connect the motor axis with the rest of the system.

If we need an even higher torque, we can use it gearbox for Nema 34 stepper motor.
