Building on the RI series’ inherent advantages of high torque density, low cogging torque, and smooth control, this series introduces a potting process that significantly enhances coil protection and overall structural stability.This enables the motor to maintain long-term, stable operation even in harsh environments characterized by high temperatures, vibration, moisture, or dust.\u003c\/p\u003e\n\u003cp\u003eThanks to its lightweight stator-rotor design and excellent thermal conductivity, the RI75‑PH KV70 delivers powerful output within an ultra-compact size. It is ideally suited for demanding applications such as exoskeleton joints, collaborative robotic arms, mobile platforms, and service robots—where space efficiency, dynamic responsiveness, and durability are critical.\u003c\/p\u003e\n\u003ch2\u003eCore Specifications\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMotor Dimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eΦ70 × 31.8 mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eThrough-hole Diameter:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e42 mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMotor Weight:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e348 g\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePeak Torque:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e3.8 Nm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNo-load Speed:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3360 rpm@48V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePotting Protection Design:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eFully potted windings provide enhanced resistance to moisture, vibration, and high temperatures, ensuring reliable operation in challenging conditions\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Torque Density:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eOptimized magnetic circuit and winding layout deliver higher torque output within a small size\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLow Cogging Torque:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEnsures smoother torque delivery and improves precision in motion control applications\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eExcellent Thermal Stability:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eAdvanced heat dissipation structure supports sustained full-load operation without performance degradation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eFlexible Integration:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eFrameless inrunner architecture allows seamless embedding into various joint modules or robotic platforms\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackaging Contents\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eRI75‑PH KV70 Potting Frameless Inrunner Torque Motor ×1\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCertificate of Conformance ×1\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0696\/3832\/4277\/files\/CubeMars_RI75-PH_KV70_Motor-sub-001.webp?v=1784197922\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0696\/3832\/4277\/files\/CubeMars_RI75-PH_KV70_Motor-sub-002.webp?v=1784197924\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0696\/3832\/4277\/files\/CubeMars_RI75-PH_KV70_Motor-sub-003.webp?v=1784197923\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0696\/3832\/4277\/files\/CubeMars_RI75-PH_KV70_Motor-sub-004.png?v=1784197925\"\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e \u003cmeta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\"\u003e\u003c\/p\u003e\n\u003cstyle\u003e\n        :root {\n            --tech-gradient: linear-gradient(135deg, #4facfe 0%, #00f2fe 100%);\n            --border-color: #d1d9e6;\n            --row-alt: #f8faff;\n            --section-bg: #e2eaf4;\n        }\n\n        body {\n            font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;\n            background-color: #f0f4f8;\n            padding: 20px;\n            margin: 0;\n            color: #333;\n        }\n\n        .table-container {\n            max-width: 1200px;\n            margin: 0 auto;\n            background: #fff;\n            border-radius: 8px;\n            box-shadow: 0 4px 15px rgba(0,0,0,0.1);\n            overflow: hidden;\n        }\n\n        .main-header {\n            background: var(--tech-gradient);\n            color: white;\n            padding: 15px;\n            text-align: center;\n            font-size: 1.25rem;\n            font-weight: bold;\n            text-transform: uppercase;\n            letter-spacing: 1px;\n            border-bottom: 2px solid #fff;\n        }\n\n        table {\n            width: 100%;\n            border-collapse: collapse;\n            background: white;\n            table-layout: fixed;\n        }\n\n        th, td {\n            padding: 11px 10px;
