(1) Performance is dependent upon heat sink configuration, system cooling conditions, and ambient temperature
(2) Values shown @ 130°C rise above a 25 °C ambient temperature, with motor mounted to the specified aluminum heat sink
(3) Peak force assumes correct rms current; consult Aerotech.
(4) Force constant and motor constant specified at stall.
(5) All performance and electrical specifications +/- 10%
(6) Maximum winding temperature is 155 °C
(7) Ambient operating temperature range: 0 °C - 25 °C, consult Aerotech for performance in elevated ambient temperatures
(8) De-rate continuous torque and continuous current by 10 percent when using an encoder
(9) All Aerotech amplifiers are rated Apk; use force constant in N / Apk when sizing
W A R N I N G: The motor case temperature may exceed 75ºC.
