(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 at maximum coil temperature, with housed motor mounted to a 305×305×12.7 mm
(4) Peak torque assumes correct rms current; consult Aerotech.
(5) Torque constant and motor constant specified at stall.
