Torque estimation of an AC compressor

Hi all,
I'm planning to drive the automobile ac compressor via a BLDC motor instead of IC engine. This is only when the vehicle is parked. Now, I'm trying to determine torque requirement. Is my calculation correct?
Power consumption: 1.46 kW
compressor speed : 1000rpm
torque=5252*hp/1000
= 14Nm

Is this value too high to be driven by a motor for a speed of 1000rpm?

Well, 14 N-m seems right.
You have a 1.46kW (2 HP) motor BLDC in your possession?

You did the calculation correctly (though a little roundabout)
