It serves as a rotary actuator for positioning and velocity control tasks in machine tools, packaging lines, and material-handling cells where closed-loop speed regulation is required. When paired with a compatible drive, it converts electrical commands into controlled shaft motion for repeatable axis movement. This makes it suitable for indexing stations, transfer systems, and other automated equipment that depends on stable servo response during repeated cycles.\u003c\/p\u003e\u003cp\u003eThis unit reaches a nominal speed of \u003cstrong\u003e1500 RPM\u003c\/strong\u003e, enabling direct coupling to gearboxes or driven shafts that operate in the low-to-mid speed range. Heat generated during load cycles is removed through \u003cstrong\u003eself-cooling\u003c\/strong\u003e, so no external fan or liquid circuit is required. Position feedback is supplied by a \u003cstrong\u003eresolver\u003c\/strong\u003e with an angular precision of \u003cstrong\u003e10 angular minutes\u003c\/strong\u003e, providing position data suitable for many mainstream motion controllers. Because this feedback method is resistant to electrical noise and temperature variation, it remains useful in demanding industrial environments. The motor uses a \u003cstrong\u003ekeyed shaft\u003c\/strong\u003e so torque can be transmitted through standard keyed couplings without additional machining. It also has motor length 2, which indicates the stack length used for this frame.\u003c\/p\u003e\u003cp\u003eCabling enters through an \u003cstrong\u003eangled swivel connector\u003c\/strong\u003e that can be rotated to direct conductors away from adjacent hardware and reduce bend stress. The housing uses \u003cstrong\u003eflange mounting\u003c\/strong\u003e, which helps align the motor with the driven load during installation. An internal \u003cstrong\u003eoil seal\u003c\/strong\u003e helps block lubricant migration along the shaft when the motor is installed near a gearhead or fluid lines. The motor has frame size \u003cstrong\u003e4\u003c\/strong\u003e, and it does not include an integrated holding brake, so any static load must be held by the drive or by external mechanical locking. This layout supports compact machine assemblies where cable routing and shaft sealing are both important.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Unstocked","offer_id":52103061274925,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/8jsa42r0015d700-0__cf0f0dc9-94b0-4a0b-930e-4a8d71e43f3b.webp?v=1778051768","url":"https:\/\/servosupplier.com\/products\/8jsa42r0015d700-0","provider":"Servo Supplier","version":"1.0","type":"link"}
