DIRECT DRIVE TECHNOLOGY LOWERS COST & IMPROVES FUNCTIONALITY
Flagstaff, AZ – Electric Torque Machines (ETM) M-Series direct drive motor systems can reduce drive system costs for electric door operators by 30% or more, as well as deliver new, advanced motion control functionality and operational advantages. ETM systems eliminate all gearing, chains, sprockets and come with almost infinite user programmable motion control functions while also decreasing electricity consumption.
Conventional door operator motors and systems require gear reductions and many incorporate chains and sprockets to achieve the torque needed at low operating speeds for lifting overhead and dock doors. These systems are bulky and over-sized, require maintenance, are inefficient, and provide minimal door motion control functions, often only a single preset speed selection and forward and reverse directions.
Advantages of ETM Direct Drive
Faster Opening & Closing – variable speed and elimination of the chains, sprockets and gears enable the door to move faster and smoother.
New Operational Features and Functionality – including programmable acceleration and deceleration profiles for “soft” start and stop, plus multiple automatic pre-set door height settings.
Improved Reliability – reduced moving parts also lowers maintenance costs.
Quiet – noticeable noise reduction due to significantly fewer rotating parts.
Improved Safety – high resolution encoder and elimination of friction (seen in conventional drives) enables more precise feedback and control, that delivers instant response to a load disturbance or an external need to stop.
Low Profile Design – high torque density motor is smaller and lower profile compared to conventional chain and geared operators.
Reduced Inventory & Handling Cost for the OEM – ETM motor and drive systems have an exceptionally large torque operating window, so OEM’s can often cover their entire line of industrial door offerings with just one or two ETM motor and drive systems. This enables much simpler inventory management, easier replacement parts service, and lower inventory costs.
Lower Energy Consumption for the Customer – using patented electromagnetic motor technology, ETM direct drive motor systems have proven energy cost savings of 60 to 80% compared to conventional NEMA motor and gearbox combinations, which operate at only 30 – 64% nominal efficiencies (common drive systems combine 60 to 80% efficient motors with 50 to 80% efficient gearboxes). This enables OEMs to meet increasing customer and government mandated energy efficiency standards, in both the U.S. and Europe.
