What is the rated output (W) of a stepping motor?
Stepping motors do not have a concept of rated output.
However, the output at a specified rotational speed can be calculated using the
following formula:
P (W) = 0.1047 × N (min⁻¹) × T (N·m)
where:
P = output (W)
N = rotational speed (min⁻¹)
T = torque (N·m)
Example:
For a 2-phase stepping motor with a basic step angle of 1.8° operating at
3000 pps (full-step) and a torque of 0.5 N·m:
W = 0.1047 × (3000 / 200 × 60) × 0.5 = 47.12 W
However, the output at a specified rotational speed can be calculated using the
following formula:
P (W) = 0.1047 × N (min⁻¹) × T (N·m)
where:
P = output (W)
N = rotational speed (min⁻¹)
T = torque (N·m)
Example:
For a 2-phase stepping motor with a basic step angle of 1.8° operating at
3000 pps (full-step) and a torque of 0.5 N·m:
W = 0.1047 × (3000 / 200 × 60) × 0.5 = 47.12 W
