BMS SERIES SPECIFICATIONS

1. Performance is dependent upon heat sink configuration, system cooling conditions, and ambient temperature.

2. All performance and electrical specifications ±10%.

3. Values shown @75°C rise above a 25°C ambient temperature, with housed motor mounted to a 250 mm x 250 mm x 6 mm aluminum heat sink.

4. Peak torque assumes correct rms current; consult Aerotech.

5. Torque constant and motor constant specified at stall.

6. All Aerotech amplifiers are rated Apk; use torque constant in N·m/Apk when sizing.
