Note:
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 300 mm x 300 mm x 13 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 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% when using an encoder.
9. All Aerotech amplifiers are rated Apk; use torque constant in N-m/Apk when sizing.
