Compact 6 RPM Gearmotor Sourcing

I need a Mandarin-speaking mechanical engineer who can quickly locate a small-form-factor AC motor with an integrated gearbox that outputs roughly 6 RPM. The task is not design work; I already know the performance I want. What I do not have is a short-list of proven Chinese manufacturers that genuinely build this type of drive and can supply it with the right certifications, dimensions, and pricing. Your job is to: • Analyse my dimensional envelope and performance notes (I will share a simple PDF and photo once we start). • Search the domestic Chinese market, speak directly with factories—not trading companies—verify catalog data, drawings, and recent production runs. • Present a comparison table that covers at least three suitable models: datasheet, outline drawing, torque curve, MOQ, unit cost at 100-piece and 1 000-piece volumes, lead time, payment terms, and any available safety approvals. • Recommend the best match and explain why, noting any risks, tooling costs, or design tweaks that may be required. • Provide direct factory contact details (name, phone, WeChat, email) so I can move straight to sample ordering. Acceptance criteria: all information must be confirmed in writing by the manufacturer, drawings must match catalogue specs, and the gearbox must meet the 6 RPM output at our stated load. A concise English summary plus original Chinese correspondence will be considered the complete deliverable.
