Power Limits

The allowable maximum power for each moteus controller depends upon the input voltage and PWM switching frequency. The below table gives the maximum allowable power at servo.pwm_rate_hz=30000.

Name Peak power High input power
moteus-r4 <= 30V 900W linear derated >= 38V 400W
moteus-c1 <= 28V 250W linear derated >= 41V 150W
moteus-n1 <= 36V 2000W linear derated >= 44V 1000W

For other values of servo.pwm_rate_hz, the allowable maximum power changes linearly with the PWM rate, so that at 15000, the maximum power is half of that in the above table and at 60000 it is double that. Note however, that efficiency of the controller goes down significantly at higher PWM rates.

The current power limit is reported in servo_stats.max_power_W. The controller will attempt to limit output phase current so as to stay within this reported power limit in either direction, i.e. applying power or regenerating energy.
