Designed for 48 VDC operation, it uses a 12-slot, 7-pole-pair electromagnetic layout with star connection, 120\u00b0 commutation, insulation class F, S2 duty, and no integrated feedback. Its main dimensions are a 38 mm stator outer diameter and an 18 mm rotor inner diameter.  <\/p>\n<p class=\"paragraph\">  This version combines high speed with useful continuous and short-term torque capability. It delivers 245 W rated power at 10,190 RPM, with 0.23 N\u00b7m rated torque and 0.76 N\u00b7m peak torque at 24.2 A. No-load speed reaches 13,000 RPM. Electrical data includes 0.14 \u03a9 phase-to-phase resistance, 0.185 mH phase-to-phase inductance, a torque constant of 0.039 Nm\/A, and a back-EMF constant of 2.88 Vrms\/Krpm. Low moving mass is supported by an 87 g stator, 20 g rotor, and 20 g\u00b7cm\u00b2 rotor inertia.  <\/p>\n<ul>\n<li>Frameless 38 mm format for direct integration into custom drive assemblies<\/li>\n<li>245 W rated output with 13,000 RPM no-load speed for compact high-speed systems<\/li>\n<li>0.23 N\u00b7m rated torque and 0.76 N\u00b7m peak torque for continuous and short-duty load demand<\/li>\n<li>Low rotor mass and 20 g\u00b7cm\u00b2 inertia support responsive drive behavior<\/li>\n<li>Suited to compact high-speed direct-drive systems using external control and feedback architecture<\/li>\n<\/ul>\n<p class=\"paragraph\">  The motor is intended for applications that require embedded installation, efficient use of space, and an external control and feedback architecture rather than integrated sensing. Its frameless construction makes it suitable for custom direct-drive designs where the motor is built into the surrounding mechanical assembly and where compact packaging and low moving mass are key design priorities.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Frameless BLDC Motor<\/p>\n","protected":false},"featured_media":70801,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[830],"product_tag":[],"class_list":{"0":"post-70794","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-frameless-motors","8":"first","9":"instock","10":"taxable","11":"shipping-taxable","12":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/product\/70794","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/media\/70801"}],"wp:attachment":[{"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/media?parent=70794"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/product_brand?post=70794"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/product_cat?post=70794"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.kocomotion.de\/en\/wp-json\/wp\/v2\/product_tag?post=70794"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
