| - | In practice these characteristics widely depend on the controller settings. At low RPMs, the secondary current (i.e. the current between controller and motor) becomes very high. If the controller settings are not carefully optimized, the controller tends to either go into "current limiting" mode and reduce the power, or to hysterically switch off completely. | + | In practice these characteristics widely depend on the controller settings. Please see chapter [[astra_conv:conversion:controller_box:controller_box#motor_controller_setup|"motor controller setup"]]! |

| - | Driving experience is therefore a bit different from what the diagram would suggest - the motor needs quite some RPMs to make you happy. The power is however sufficient for accelating with ease and without feeling the constant need to "apologize" to the drivers behind you. | + | |

| - | The motor is fitted for liquid cooling. Initially, it even worked without (at moderate ambient temperatures), but meanwhile liquid cooling is installed, together with forced air cooling of the motor controller. Please see chapter [[astra_conv:conversion:cooling_system:cooling_system|"cooling system"]] below. | + | |

| - | Please note that the fittings used in below foto turned out not to be tight - I have changed them later. The new fittings have a flange to press a rubber gasket against the motor's case. | + | |
