{"product_id":"dunkermotoren-e-38-r-power-off-brake","title":"Dunkermotoren E38R Power-Off Brake","description":"\u003cp\u003eThe Dunkermotoren E38R is a spring-force power-off brake that holds a motor axis the instant supply voltage is removed, so vertical loads, positioning stages and gravity-loaded axes stay put through an emergency stop or power failure. Because the holding force comes from a spring rather than a permanent magnet, torque stays predictable as the motor heats up or the duty cycle changes, and there's no polarity to get wrong on connection.\u003c\/p\u003e\n\u003cp\u003eThe E38 brake integrates directly into Dunkermotoren's BG45XI motor housing (BG45x15 and BG45x30 variants) at IP65, with engagement controlled by the motor's own software rather than a separate switching circuit. Where a standalone mount is preferred, it can also be fitted openly or under a cover, connecting via 300mm grey leads (UL style 1569 AWG 24) to a 24Vdc supply.\u003c\/p\u003e\n\u003cp\u003eIts combination of fast engagement and compact Ø38mm body suits small servo and stepper axes where a vertical load, clamp or positioning stage must not drift the moment power is lost, typical in general motion control, factory automation and small robotic axes.\u003c\/p\u003e\n\u003cp\u003eIt's part of Dunkermotoren's full power-off brake series, which spans the permanent-magnet E22R and E100R through to the higher-torque spring-force E90R, E310R and E600R for larger axes, plus the power-on E46A to E605A range for applications requiring a normally-braked default state.\u003c\/p\u003e\n\u003cp\u003eAll rated values apply in the run-in condition.\u003c\/p\u003e","brand":"Powerbox Australia","offers":[{"title":"E38R","offer_id":44601200771123,"sku":"E38R","price":0.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/5960\/0435\/files\/dunkermotoren-e38r-spring-applied-power-off-motor-brake.png?v=1785374117","url":"https:\/\/www.powerbox.com.au\/products\/dunkermotoren-e-38-r-power-off-brake","provider":"Powerbox Australia","version":"1.0","type":"link"}
