Direct drive motors are either linear or rotary motors and are an integral part of the mechanical assembly.

. Get Fast Reliable Shipping. While brushless motors have been around for a very long time the detailed application of this technology has countless variants. New Ways of Integrating Direct drive motors have been incorporated in many standard applications for a while but as machine builders have become more familiar with the technology theyve come up with new ways to take advantage of direct drive.

A Direct Drive Motor can be used for various applications such as applications where a high positioning accuracy is needed. Torque motors are often used in rotation stages for precision positioning and automation applications. While these characteristics make direct drive devices excellent for many positioning and motion control applications there are some considerations where an indirect drive option may be more suitable because direct drive devices.

They have limited applications -. Direct drive motors also have lower noise production than conventional motors which is important for noise-sensitive applications like those in the medical and laboratory industries. As a result the amount of moving parts in the system is reduced tremendously increasing the efficiency and creating a quiet and high dynamic operation.

Torque and force for torque and linear motors respectively allows the machine to take up less space overall without having to sacrifice power. Direct-drive mechanisms are used in applications ranging from low speed operation such as phonographs telescope mounts and ski lifts video game racing wheels and gearless wind turbines to high speeds such as fans computer hard drives VCR heads sewing machines CNC machines and washing machines. More recently manufacturers have developed direct drive motors designed for easy integration.

Moreover these frameless motors are used for situations where small size low weight maximum power and optimal. One of the key advantages of direct drive motors is the high performance they deliver relative to their footprint. And like HEIDENHAIN ETEL builds its linear and torque motors along with motion systems on a foundation of superior knowledge and.

Magnets are attached to the rotor of the motor and windings are. When combined with frictionless air bearings they provide virtually unlimited service life Figure 14a. These converters control motors in 2- and 4-quadrant operation and are available in a broad power range from under 05 kW to beyond 1 MW.

Without additional transmission elements direct drive motors tend to be more compact than traditional motors making them easier to integrate into machines and systems. Solutions range from high-end motion systems with nanometer precision to industrial applications requiring high torque. Direct drive motors are commonly used in the medical aerospace defense and industrial sectors.

Therefore direct drive technology achieves a very high lifetime. The components need to be attached aligned axially and mounted with feedback device. ETEL has developed a curved linear motor track for its direct drive linear motors and it will be released this year.

Direct Drive motors either housed rotary DDR cartridge rotary CDDR or frameless KBM high-voltage rotary or TBM low-voltage rotary or. Typical applications include pumps fans and motors for technological processes. And outside of the size profile this is the most.

Direct Drive Motors and Motion Systems. Increases in force density. Applimotion motors and actuators utilize rotary and linear brushless motor technology to create unique motion solutions.

When you feel the need for speed direct drive technology can help maximize the productivity of your machine. An increase in demand for greater energy efficiency due. Rotation stages based on direct drive torque motors exhibit zero play and backlash unlike worm-gear driven stages.

The motors essentially eliminate the need for mechanical transmission elements such as couplings gearboxes or belt and pulley systems. Typical examples of direct drive applications are found in gimbals such as antenna systems eg vehicle mounted satellite communications surveillance CCTV cameras scanners telescopes electro-optics rate tables and radar systems. Although friction is generally seen as an undesirable effect of relative motion between two components the reduced friction inherent in direct drives can be a downside in some applications.

Mechanical transmission such as gearboxes timing belts pulleys or lead screws introduce backlash mechanical losses and objectionable audible noise that can reduce machine performance increase machine size and weight. Direct drive mechanisms are present in products such as fans washing machines sewing machines wind turbines and more. Lack power off stability Can generate significant heat at the load and require.

Kollmorgen KBM Direct Drive Rotary Motor Indexing Application. Characteristics And Application Of Dc Motor Mechanical Energy Electronic Parts Application The Ecowatt Drive Is A Variable Frequency Drive That Allows Easy Motor Pairing And Performance Contro Energy Saving Features Ventilation System Centrifugal Fan Pin On Dc Motor 104mm Brushless Dc Motorcycle 36v Electric Motor High Torque Direct Drive Motor Electric. The higher accelerations enabled by direct drive technology can shave precious milliseconds from your index times and increase your throughput.

For example with direct drives there is very little resistance to back driving so a linear direct drive system used in a vertical application will require an external brake or. Direct Drive Motor Technology. Frameless direct drive motors take a lot of work to design it in says Jeff Arnold Product Specialist at Kollmorgen Santa Barbara California.

Ad Search Graingers Online Catalog. One example of this is how linear motors have been used to provide torque. One of the most frequent applications is for use in gimbals in antennas and satellites due to the reliability and dynamic motion created by direct drive engines.

Our team of engineers work closely with the customers to understand their application and create. HEIDENHAIN offers the largest direct drive motor range on the market via ETEL. In direct drive torque motors the motor directly drives the load which eliminates the use of a transmission or a gearbox.

These motors are in common use. In terms of quantity general low-voltage drives for universal applications are the largest area of use for frequency converters.
