The golf vehicle controller appears lacks the breakdown

The controller one of as golf vehicle most core’s parts, it in uses in the process, if operates, when easy to appear lacks the phenomenon, lacks the appearance can create electric bus the vehicles asthenia to have, the rotational speed low status question. The controller lacks divides the main phase to lack and Hall lacks.
The main phase lacks us to be possible through to have examines the MOS tube also to penetrate, when replacement should also replace. The golf vehicle Hall part lacks displays cannot distinguish the electric motor Hall signal for the controller. The examination method is: electric car Opens out the controller with not to brush electric motor’s Hall lead wire, under the controller circular telegram condition, with avonmeter’s DC voltage files, the black pen depending on in the controller Hall lead wire’s heavy line, the red table pen surveys controller’s other Hall lead wire, should have the 0-5V above voltage change, otherwise the explanation controller interior Hall output circuit presents the breakdown. Through surveys the Hall lead wire the filter electric capacity and the master control chip corresponding post, further diagnosis position. The replacement filter electric capacity or the electric truck replacement master control chip may the trouble clearing.
The golf vehicle’s electric motor lacks is generally by not brushes electric motor’s Hall part damage to cause the place. May through survey the Hall part output lead relative Hall grounding and the Hall power source lead wire resistance, which Hall part is presents the breakdown only electric van with the comparison test judgment.
For guarantee electrically operated golf vehicle electric motor phase change position’s precise, the suggestion simultaneously replaces all three Hall part generally. Before replacing the Hall part, must clarify electric motor’s phase algebra angle is 120 degrees or 60 degrees. Generally 60 degree phase angle electric motor’s three Hall part places the position is parallel. But 120 degree phase angle electric motor’s three Hall electric tourist bus a part middle Hall part is assumes turns over 180 degrees positions to place. In the actual service, best records the Qingyuan electric motor Hall part’s installment position, carries on the installment according to its original position, in order to avoid creates time the unwanted response the electric motor does not transfer.
