Argon user guide/Motor compatibility

This is a short guide for determining whether or not a motor is suitable for Argon.

Motor type must be one of the following (rotary or linear):

  • Permanent magnet brushed DC
  • Permanent magnet brushless DC (BLDC) (magnetic pole count 2 to 100)
  • Permanent magnet AC (magnetic pole count 2 to 100)

Servomotors must be equipped with an compatible Feedback devices. If motor is equipped with encoder, following types are compatible:

  • Encoder voltage 5V
  • Outputs single ended or differential
  • 2 channel encoder is enough for all motor types
  • Suitable encoder resolutions are from about 100 PPR to 131070 PPR (pulses or lines per revolution)
  • Index channel is not required but is supported for precise homing
  • Hall or commutation sensors are not required but are supported for AC/BLDC motors

Motor voltages and currents can introduce some limitations to motor output speed and torque but will not cause unsuitability.

  • Motor voltage is the limiting factor for maximum speed. For example, if you have a 200 VDC brushed DC servo motor and run it at 115 VAC using Argon, then you can expect to get a speed of 115*1.41*88%*/200V = 71% of motor's rated speed. 88% comes from Argon's effective voltage swing at power outputs (see Argon specifications).
  • Motor current is the limiting factor for maximum torque. For example, if you have motor rated for 20A DC and drive's maximum output is 10A DC, then you get 50% of the rated torque.

Argon has high dynamic range torque control which makes it suitable also for very small motors, such as ones with rated current around 300 mA.
