The motor and controller for the E-Hawk have arrived. We decided on the Rotex Electric REX30 Motor and the HBC series controller from MGM Compro. The plan is to run the motor at either 86V (24s) or 100V (28s) depending on the battery we end up with. The motor is rated at 20kW max, and 8kW continuous. The motor is a 4-turn wind which yields a kV of 40 rpm/V. The controller is designed to work up to 120V and 280A continuous. The weight of motor and controller are 5.2 kg and 1.5 kg respectively.
In this installment of the blog we also design and build a minimal electrical system consisting of a small battery pack, circuit breaker, some enable switches, and a potentiometer. This allows us to power-up the system, learn how to configure the controller, and perform some preliminary tests.
