(1) Performance is dependent upon heat sink configuration, system cooling conditions, and ambient temperature.
(2) All performance and electrical specifications have a tolerance of ±10%.
(3) Values shown @ 100 °C rise above a 25 °C ambient temperature, with motor mounted to the specified aluminum heat
sink.
(4) Peak force assumes correct rms current; consult Aerotech.
(5) Force constant and motor constant specified at stall
(6) All Aerotech amplifiers are rated A
