Hello, of course, an asynchronous motor can provide torque at speed zero. Otherwise it would not be able to accelerate avertical load. The motor holding brake is a safety device which ensures a not dropping loadin case of motor error.Even some crane applications need to position, think about container cranes for cargo shipping,therefore servo motors (asynchron and in some cases synchron) are applied: https://www.automation.siemens.com/mcms/infocenter/dokumentencenter/mc/Documentsu20Catalogs/CR1-2012-en.pdf |
