AGP Introduces High-Frequency Coring Motor, Drill Stand
Published: 24/7
AGP’s DM20 is an all-new rig mounted coring motor for 4- to 19.6-in (100- to 500mm) diameters. It is said to be able to accomplish this with only one gear ratio due to its state-of-the-art high-frequency motor design, which allows a wide speed range with no loss of torque. There are no gears to select with all speed adjustments being made electronically via the digital interface. Users simply select the diameter by pushing a button, and the user is ready to drill. Although it is high-frequency, no separate power box or three-phase power are needed. All features are integrated into a single motor head that runs on single phase 220-240V
On 16A input, the DM20 puts out 4.4 hp (3.3kW), which AGP says is 90% efficiency. Noting that a typical 16A universal motor puts out only about 2.8 hp (2.1kW) or less on the same input, AGP says DM20 is more than half again as powerful as other units available. AGP is also very proud of its permanent magnet synchronous motor (PMSM) technology, the first such application for a coring motor.
In addition to performance, AGP says that there are many useful features built into the design. The display can be easily switched between inches and millimeters, while a clearly visible LED load indicator enables the operator to optimize feed pressure. Running on single-phase current makes the whole system much easier and more convenient to set up and run
In addition, AGP has introduced the QS600 drill stand, which features a quick-release camlock cradle system. This makes it much easier and safer for the operator to mount and dismount the motor, especially when dealing with walls and similar situations. Another distinguishing characteristic of the stand is its ability to mount up to a 19.6-in (500mm) core bit without the need for any additional spacer. It can also mount a 23.6-in (600mm) bit with the addition of an accessory spacer.
This drill stand has a full range of features, such as built-in gear reduction, tilt capability, spirit levels, and wheels. The rig has been designed and built for strength but with minimized weight, using a steel reinforced aluminum alloy column and box steel base.
