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)
- Permanent magnet AC
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.
