{"product_id":"dunkermotoren-e-90-r-power-off-brake","title":"Dunkermotoren E90R Power-Off Brake","description":"\u003cp\u003eThe Dunkermotoren E90R 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, its 1Nm nominal torque (0.60–1.20Nm over the temperature range) stays predictable as the motor heats up or the duty cycle changes.\u003c\/p\u003e\n\u003cp\u003eIn combination with Dunkermotoren's brushless motors the E90R integrates into the motor's profile housing at IP65, pairing with BG66 and BG75 motors in that configuration. Where a standalone mount is preferred, it can also be fitted openly or under a cover, connecting via 300mm grey leads (UL style 1569 AWG22) to a 24Vdc supply.\u003c\/p\u003e\n\u003cp\u003eThe E90R is also available with manual unlocking and with manual release; on the release version a Ø3.6mm hole in the lever takes a Bowden cable, so an operator can free a jammed axis from the front or the rear without power. Its 1Nm holding and mid-range Ø59mm body suit general-duty servo and stepper axes where a vertical load, clamp or positioning stage must not drift the moment power is lost, typical in motion control, factory automation and machine build.\u003c\/p\u003e\n\u003cp\u003eIt's part of Dunkermotoren's full power-off brake series, which spans the permanent-magnet E22R and E100R and the spring-force E38R, 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":"E90R","offer_id":44603263549491,"sku":"E90R","price":0.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/5960\/0435\/files\/dunkermotoren-e90r-spring-applied-power-off-motor-brake.png?v=1785374165","url":"https:\/\/www.powerbox.com.au\/products\/dunkermotoren-e-90-r-power-off-brake","provider":"Powerbox Australia","version":"1.0","type":"link"}
