Motors and Inverters for Electric Aircraft Testbed

We are requesting the purchase of a commercially available motor/inverter combination and require inverter and motor with the following specifications: �Compatible with each other �Inverter CAN bus communication signals compatible with page 13-17 of the attachment �Must be compatible with previously purchased Rinehart (PM150DZ) and Parker Motors (Parker GVM210-300Q6 Motor) �Samarium Cobalt Permanent Magnet Motors for high temperature operation �250kW continuous power for the motor and inverter �1Mb/s CAN bus communication rate �Dimensions inverters must be within our envelope: 400 X 400 X 840 mm �Dimensions of 250kW motors must be less than 400 mm diameter, 500 mm length �Inverters and motors must be able to operate together and be tuned �Inverters and motors must be able to operate either all together as a 1MW system load or drive using four 250kw motors on a single shaft at speeds greater than 6800 RPM �Inverters and motors must be able to operate on a single shaft with two motors acting as a 500 kW drive and two motors acting as a 500 kW load at speeds greater than 6800 RPM. �Speed and torque control support �Must provide four quadrant support in both motors/generators and inverters/rectifiers �DC link voltage between 600V and 900V �Liquid cooled �Dual connected motors (two 250 kW motors pre-connected) so that only two dual connected motors are required to implement four motors on a single shaft
