2021 Hyperdrive Manufacturing Update # 2

In this article we reveal you exactly how the electric motor windings, stator and also circuit card all obtain put together right into the customized electric motor warmth sink.

The Hyperdrive outcomes a market leading power to weight of 176 watts per kg. In order to safeguard the electric motor from a thermal runaway getting too hot occasion we construct a thermistor circuit that keeps track of the warmth in the windings and also will certainly activate the controller to transform the electric motor off if the electric motor reaches 125 levels.

The circuit consists of a resistor, thermistor and also some arbitrary cables!

It obtains contributed to the electric motor control panel and also connects with the controller temperature level setups. We likewise change the controller stage cables to make sure that they affix straight to the electric motor windings.

The electric motor heatsink obtains warmed to 300 levels which enables the windings to be put inside and also to be diminished in position as the light weight aluminum heatsink cools down.

The heatsink is warmed to 300 in order to move the windings right into location.

Right here the raw windings are close to the heatsink.

Eye sweet!

Next the electric motor stators are furnished with a brand-new large covered bearing, and also the pinion shaft is accuracy fit and also protected to the stator with unique high bond lock tight, in addition to being pinned with a development roll pin. This dual redundancy makes certain no problems.

At this moment the electric motor board, including the hall sensing units, temperature level circuit and also stage cables is included and also the stage cables are soldered straight onto the windings.

There are a pair a lot more actions essential prior to the electric motor construct is full. These will certainly can be found in the following blog post. What you see right here is a personalized, rebuilt electric motor that enables phenomenal outcomes!
