− | + | *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 '''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 voltage''' is the limiting factor for maximum speed.
