direct drive motor applications

No Gearbox No Oil No Contamination. This makes it a very efficient and energy saving solution for those looking to save on energy costs.

Characteristics And Application Of Dc Motor Mechanical Energy Electronic Parts Application

Direct-drive technology the force of a motor being directly applied to a mechanism without any intermediate drivetrain such as a gearbox or toothed belt has been around for more than 40 years but some machine builders still may not fully appreciate its benefits.

. Changing the direction of current changes polarity and changing the amount of current changes the magnetic force. Lebanon OH--Most servo systems are complex. The Advantages of Direct-Drive Technology for Manufacturing.

Torque and force for torque and linear motors respectively let machines take up. Direct Drive Servo Drives and Motor controllers Range Select the option that best fits with your project requirements or contact us for advice. Direct Drive Motors are very suitable for high speed acceleration applications with fast starts and stops.

Appears in Print as. Direct drive motors either housed rotary ddr cartridge rotary cddr or frameless kbm high-voltage rotary or tbm low-voltage rotary or ddl linear motors directly mount to the load to be driven thereby eliminating the transmission providing a much more robust alternative want to know more about frameless motors or direct drive linear. The friction and compliance inherent in mechanical transmission components can also provide damping for vibrations and oscillations whereas direct drive systems typically provide less damping for these effects which can mean an increase in settling time.

Direct drive torque motors deliver high torque over a wide range of speed from a stalled or low speed condition to high angular velocities. 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.

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. Furthermore they can also be supplied as frameless motors. Direct drive motors are commonly used in the medical aerospace defense and industrial sectors.

It started with machine tools Direct-drive linear DDL motion technology had its start in the machine tool industriesin applications such as high-quality machining honing grinding punching and laser cutting. The core working principles of direct drive motor technology is in essence based on the right hand rule of electromagnetism whereby a current moving through a wound coil creates a magnetic field Figure 1. The capability of the motor to integrate into the existing system is crucial to avoid installation maintenance and ease of usability.

In direct drive torque motors the motor directly drives the load which eliminates the use of a transmission or a gearbox. OEMs and integrators often cite the high cost of direct drive motors as their major. LiveDrive is the new standard for working above food pharmaceuticals electronics and packaging lines.

It eliminates the need for additional interfacing and as such reduces the cost of ownership. A direct drive motor is one that uses the electrical power coming from an external motor with no internal losses. 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 14 15 16 to high speeds such as fans computer hard drives VCR heads sewing machines CNC machines and washing machines.

These precision drives are frequently used to control 2-quadrant operation of motors in machine tools industrial robots etc. Little to no maintenance required Compact sizes Highly reliable Clean mechanical assembly Improved accuracy Low cooling requirements Lower noise production ideal for noise-sensitive applications Higher throughput Allows for more compact systems to be designed. Therefore direct drive technology achieves a very high lifetime.

The power range is predominantly between 05 kW and 30 kW. Direct drive motors are made using two or more separate motors working in parallel to give the same result as one motor with one part. There are many advantages to using a direct drive motor within your mechanical assembly.

Explore our range of standard and custom servo drives for direct drive motors and find the right solution for your application. Highly dynamic servo drives are used in applications with high peak loads for controlling position speed or torque. 5-60 VDC CANopen 50 kHz Update Rate 10 A 500 W.

While torque motors can achieve high velocities up to 5000 rpm there is a trade-off in torque as the motor. Manufacturers come up with ways for the smooth integration of the motor these days. This is because they only need low torque to accelerate the motor compared to geared motors which have a lower torque to inertia ratio.

For Hygienic Applications Every manufacturer wants to maximize product quality and cleanliness however current drivetrains operate with a gearbox full of oil directly above the product. Direct drive motors are used in sync with the technology that is already established in the industry or a particular facility. They typically contain motors drives gearboxes belts pulleys sensors and power-transmission shafts oft.

Advantages and Applications of Custom Direct Drive Motors Special Voice Coil 3 Phase Linear Torque Designs 1. High Dynamics Custom Motors Instrumentation equipment and precision automation systems manufacturers rely on motion components in applications from optical scanning to micro-mechanical assembly. Torque motors are often used in robot applications.

Furthermore a direct drive motor can also be supplied as a frameless motor which is one without a frame housing bearing or feedback system. One of the key advantages of direct drive motors is the high performance they deliver relative to their footprint. Several linear motor design variants exist.

The advantage of a frameless motor is that system suppliers can integrate it into an application easily.
