Brushless Deck Motor Assembly
The BLDC motor experiences high thermal stress and mechanical vibration during operation. Failure typically occurs when internal hall effect sensors drift or windings short-circuit due to moisture ingress or insulation breakdown from excessive heat under heavy commercial loads. This assembly replaces the entire mechanical and electromagnetic drive unit.

Deck Motor Controller (Inverter)
The controller uses power MOSFETs to convert DC battery power into three-phase AC for the motor. If a blade hits a fixed object, the resulting current spike can cause 'thermal runaway' or FET punch-through in the controller, preventing the motor from initiating its start-up sequence even if the motor itself is physically intact.

Deck Power/Communication Harness
Electric ZTRs rely on a constant handshake between the VCM and the deck motors via a low-voltage data line. Vibration-induced pin fretting or 'creep' at the connector terminals can cause intermittent signal loss, which the system interprets as a motor fault, triggering a safety shutdown of the deck.
