(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 a 250 mm x 250 mm x 6 mm aluminum
heat sink
(3) Peak torque assumes correct rms current, consult Aerotech
(4) Torque Constant and Motor Constant specified at stall
(5) All performance and electrical specific/- 10 percent
(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 torque constant in N-m / Apk when sizing
3.4. Load Capability
The ASR1100 is designed for tubular manufacturing applications. With this in mind, the tubes loaded into the
collet chuck of the rotary axis must fall within the max load parameters outlined in Table 3-2.
N O T E : Maximum loads are mutually exclusive; loading limits are due to the collet chuck mechanism.
Contact Aerotech directly if part load requirement exceeds specifications.
