Direct drive is a very advanced piece of technology, to the point where each one of the design concepts can be developed into fruitful technology.
Fremont, CA: Direct drive motor technology has been around for many years. The advancement of the technology is slow due to the factor of difficulties in developing and applying new methods. Even those who approve of such new methods find it difficult to change the set technologies that are good enough at present. Despite that, many industrialists choose to develop such technology and advance the production or business, even it is limited by what the builder is able to implement.
In today’s highly competitive world, the more one understands the advantages and benefits of direct drive technology, the more they will have an advantage in machine building, giving them an edge over their competition. Direct drive is a very advanced piece of technology, to the point where each one of the design concepts can be developed into fruitful technology.
Below are three advancements that direct drive motor builders are taking to ensure the customer gets the most out of their capabilities.
Efficiency is always in demand for the motor that is to be installed always. Manufacturers keep looking to produce greener motors with novel designs that can keep power loses at a minimum, including lamination stack, which the coils wind around, out of incredibly small layers to reduce Eddy currents, utilizing Litz wires for the coil windings, and segmented magnets. Motor makers are also looking into the different type of materials to efficiently piece together the motor to obtain the most efficient performance from a standard device.
Direct drive motors are used in sync with the technology that is already established in the industry or a particular facility. The capability of the motor to integrate into the existing system is crucial to avoid installation, maintenance, and ease of usability. Manufacturers come up with ways for the smooth integration of the motor these days. Two of which is in-machine tool liquid cooling and consistent magnetic way methods.
To help ease these concerns, motor manufacturers now often provide the option of standalone, built-in closed-cooling jackets. These all but eliminate coolant leakage and the challenge of designing optimum cooling channels.
If a similar magnetic way track can be used across multiple motor models it will be much easier to adjustment the motor changes. The benefit is better if the next-generation models can still use the original tracks allowing the customer to upgrade their machine with minimal effort.
Increase in Force Density
The advancements in the machine tool industry look forward to how to maximize the force density within a volume. By fitting more copper coils densely packed within the specified volume can create stronger magnetic flux. Also enabling higher heat dissipation capability can cool the device better with minimal side effects to the motor, leading to better performance too. By efficiently designing and tweaking the parameters and materials machine manufacturers can increase the torque and force output of the direct drive motor.
