For amplifiers using peak sinusoidal ratings, multiply RMS sinusoidal Kt by 0.707 and current by 1.414. Specifications subject to change without notice. Refer to performance specifications for availability of 3 stack stator by stroke/lead combination. Test data derived using NEMA recommended aluminum heatsink 10" x 10" x 1/4" at 25°C ambient.
