Power-Off Brake Engagement — Safety Without Dependence
Mechanical parking brakes on cargo tricycles work by cable tension on a drum or disc. Every component — cable, lever, pad, spring — wears independently, and failure at any point means failure of the entire system. An electromagnetic brake operates on the opposite principle: spring-loaded engagement, electromagnetically released. Power on → brake releases. Power off → brake locks. No cable to stretch, no pad to glaze, no lever to adjust. A brushless DC differential motor with parking brake sourced from Kehuan engages automatically when the key is turned off, when the battery disconnect trips, or when any electrical fault cuts power to the controller — exactly the moments when mechanical brakes are least reliable.
Factory-Matched Motor + Controller — No Integration Guesswork
A brake motor is only as good as the controller that drives it. Kehuan manufactures both the KH120 motor and its matched controllers in the same ISO 9001:2015 certified facility. The electromagnetic brake release timing and current draw are tuned against Kehuan's own controller firmware — not derived from third-party datasheets. When you source a high torque e-rickshaw motor 1800W with brake from Kehuan, you receive a pre-validated motor-controller pair. No oscilloscope, no trial-and-error phase matching, no burned windings from incorrect timing advance.
Built for the Worst Road — IP54, H-Class Duty Cycle
KH120 motors are sealed to IP54 — dust-protected and splash-resistant — and rated for S1 continuous through S9 non-periodic duty cycles. This means the motor handles sustained full-load operation on a 10 km uphill delivery route at 40°C ambient temperature without thermal derating. For distributors serving rural and semi-urban markets where road conditions destroy under-spec motors within months, this matters more than per-unit price.
One Chassis, Seven Configurations — Customize Without Redesign
The KH120 electromagnetic brake motor is part of a 7-variant series sharing the same mounting footprint: straight gear, helical gear, square-flange, T-type, flange, and standard differential variants. If your OEM customer later needs a non-brake variant for flat-terrain markets, the chassis integration does not change. One frame design, one supply chain, seven motor configurations.
