brushless motor 101?
brushless motor 101?
(OP)
Hi, I am bidding a project- therefor do not want to put in a ton of time upfront before getting a PO from a client.
Typically, we use 2 and 4 pole 3 phase motors. For this project, we are looking at a battery powered system, hence the brushless question.
I am looking for 4-8 shaft HP, operating at (probably) 120VDC. I would rather avoid a gear box. I am driving a hydraulic pump. In order to estimate the pump, I need to know the likely motor speed.
Question: is there an optimal, or nominal speed for a brushless motor of this size (I am used to 3 phase motors, which have fixed RPM). the faster I can expect the motor to operate, the smaller the pump I can source (up to ~3000 or 3600 RPM).
thanks
