Hello, I have 2 Baldor BSM-90N-375AA Servo Motors and 2 Baldor BSC1115 servo Drives. My question is if this 2 can work together. My concern is that the motor is 19A Cont. stall current and the drives are 15A ARMS.

The Servo Motor specs. are :

General Parameters
Cont. Stall Torque Lb-In (N-m): 117.00 (13.30)
Cont. Stall Current: 19
Peak Torque Lb-In (N-m): 470.82 (53.2)
Peak Current: 68.4

Electrical Parameters
Torque Constant Lb-In/Amp (N-m/Amp): 6.88 (0.78)
Voltage Constant Vpk/KRPM (VRMS/KRPM): 66.4 (46.95)
Resistance: 0.21
Inductance (mHy): 0.6

Mechanical Parameters
Inertia Lb-In-s2 (Kg-cm2): 0.0082 (9.2578)
Speed at 300 Bus Volts (RPM): 4000
Max Speed (RPM): 7000
No. of Motor Poles: 08

Feedback Device
Resolver
Speed: 1 SPEED

And the specs. for the drive:

BSC Servo Control Specifications: 230VAC

Input voltage 230V–3φ

Nominal Bus Volts 300 (280–350)

Continuous Bus Current ARMS 15
Peak Bus Current (1.5s ±.5s) ARMS 30
Recommended Fuse Size  A 30
Continuous Output Power Rating kVA 6.5
Simulated Encoder Output ppr 250/500/1000/1024
Efficiency % >95
Nominal Switching Frequency kHz 8.5
Minimum Load Inductance μH 200
Analog Command Input VDC ±10
Speed Command Potentiometer 5kΩ or 10kΩ, 0.5watt
Balance (Offset Drift) RPM Adjustable to 0

Thank you.

the best choice to drive bsm series motors is either flex drive or microflex - look up servo systems - they are a good baldor dealer who can get either of those products - they can also have a baldor tech answer questions about your current equipment.
