Brushless DC Motor Diagnostics
The drive unit is the heart of your system. In Canterbury, we troubleshoot high-torque DC motors, replacing worn carbon brushes or faulty encoders to restore silent operation.
Telescopic Door Alignment
Telescopic doors in Canterbury require precise belt synchronization. We align the slow and fast leaves to prevent jamming and ensure maximum opening width.
Weather Mode Programming
Winter in Canterbury is cold. We program 'Partial Open' modes (e.g., 50% width), keeping heat inside while allowing pedestrian access.
Kevlar Drive Belt Tensioning
A loose belt causes 'juddering'. We install reinforced Kevlar timing belts and tension them to factory Newton-meter specs, ensuring smooth acceleration for your Canterbury entrance.
Heavy Duty Operator Install
For massive glass leaves in Canterbury, standard motors fail. We install heavy-duty operators capable of moving 200kg+ doors effortlessly.
