Motion Control – Compact High Force Iron Core Brushless Linear Motor!

 

H2W Logo

Santa Clarita, CA —- Motion Control – H2W engineers have developed a compact high force brushless linear motor (BLSM-1F) that can generate 300 lbs [1330 N] at a 10% duty cycle and 100 lbs [444 N] at a 100% duty cycle, and, when used with a matching magnet track (BLST-FSX). The mass of the coil assembly is 19 lbs [9 Kg] which gives a force to moving mass ratio of 15:8

The motor can be driven using either a trapezoidal or digital standard three phase brushless amplifier. The Brushless Linear Motor Coil measures 6.53 in X 7.50 in x 1.50 in [170 mm x 190 mm x 38 mm]. This Brushless Linear Motor is designed for applications that require a wide speed range and a relatively high force. This motor is encapsulated using high temperature 350°F [176°C] thermally conductive potting compound which protects the components and seals it from dust and moisture.

The 3-phase brushless linear motors, also known as an AC linear servo motors, are direct drive motors that are ideal for long stroke, closed loop servo, linear motion applications. They can be used at speeds up to 240 in/sec [6 m/sec]. They are capable of very precise position, velocity and acceleration control when coupled with a linear encoder for position feedback.

The laminated 3 phase wound coil assembly is used in conjunction with a linear magnet track to produce a controlled linear force. A customer supplied bearing system is required to maintain the .060 in [1.5 mm] air gap between the coil assembly and the magnet track. There is a relatively large attractive force between the motor coil and the magnet assembly. The magnet track consists of rare earth neodymium magnets and the require overall length is equal to the coil assembly length plus the stroke length.

Advantages:

  • Uses a standard three-phase brushless amplifier
  • Multiple coils can operate on the same magnet track assembly
  • Unlimited stroke length
  • High force to moving mass ratio
  • The magnetic attractive force between the coil and magnet track assemblies creates preload for a bearing system

Typical Brushless Linear Motor Applications:

  • Conveying Systems
  • Baggage Handling
  • Coordinate Measurement Machines
  • Laser and Water Jet Cutting
  • Pick-and-Place Machinery

Fall River, MA –Motion Control Components – Miniature Encoders – Requirements on encoders are becoming more and more demanding. This applies particularly to positioning applications with precision constant-speed control, where increasingly compact housings need to accommodate an ever greater number of electrical contacts. maxon motor solves this problem with its new ENX 16 RIO optical encoder. It is a mere 16 millimeters in size and offers a resolution of up to 65,536 counts per turn, making it ideal for the precise position and velocity control of DC motors

The new maxon ENX 16 RIO encoder (Reflective, Interpolated, Optical) fulfills all the requirements for a high-resolution optical encoder in a compact design. The resolution can be configured at the factory or online. With 16 millimeters outer diameter and 7 millimeters overall length, the housing is mechanically robust and protected from dust due to its injection-molded construction. The operating temperature range is -40 °C to +100 °C.

Motion Control – Highly Efficient 2 Way Traction Drives Reduce Motor Torque Ripple up to 84%!

North Babylon, NY – Motion Control Components – Rolling Motion Industries (RMI) has released two new traction drives. The MAR-17-2-2.1 Traction Drive and the MAR-23-2-2.1 Traction Drive. These highly efficient 2-Way gearless traction drives with only six moving parts use an engineered traction fluid with a coefficient of friction of just 0.1 to 0.12. The MAR-17-2-2.1 and MAR-23-2-2.1 Traction Drives have demonstrated an up to 84% reduction in motor torque ripple when measured at the output shaft of the motor and then measures at the output shaft of the traction drive. The MAR17-2-2.1 Traction Drive is designed for speeds to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-2-2.1 Traction Drive is rated for 3600 rpm with 20 to 30 in/lbs of torque.

Having no metal to metal contact these compact, high efficiency drives generate up to 72% less heat after 24 hours of continuous operation, and these permanently lubricated traction drives typically last three times longer than conventional gearboxes, They also create up to 38% lower dB at 3000 rpm than conventional gearboxes which is less than a typical home appliance. Even though there is no metal to metal contact there is no slippage or lost motion between the input and output shafts.

Operating at temperatures that are lower than a motor’s, with low vibration, and no torque losses from 10 to 3000 rpm, these traction drives permit a motor to operate at peak efficiency. Applications for these 2-Way traction drives which can operate in explosive environments (ie. zone 1 and 21) include: Medical (including patient handling), pharmaceuticals, wafer handling, robotics, conveyers, sorting, pumps, assembly, battery operated vehicles, and other power transmission and motion applications.

These revolutionary drives are available with an optional overriding clutch. Incorporating standard NEMA mounting dimensions, these drives can be easily integrated into new and existing applications.

About Rolling Motion Industries (RMI)-

About Rolling Motion Industries (RMI): In 1993 John Pawloski and his brother Ray took over the family business, Jewelers Machinist Co. They realized they needed to switch from outdated conventional thread grinders to CNC thread grinders. As a result, Jewelers Machinist Co is recognized as the source of some of the most complex thread grinding in the industry. The concept for the RMI traction drive came from John in 2007. Working in that high precision industry aided John in the development of the RMI Traction Drive.

In the years that followed, the design of the individual components and formula of the engineered traction fluid were finalized, testing was completed, a patent granted, and production begun. The RMI Traction Drive is one of the most efficient ways to transmit power from one point to another. Utilizing rolling motion, RMI is able to transfer power at various ratios with minimal energy loss. Tested against V-belt, direct drive, chain, and gearbox setups, RMI Traction Drives offer energy saving benefits through true efficiency rating percentages up to 98%. The high efficiency of the traction drive allows electric motors to run at their peak efficiency ranges.

There are many applications where it can be used from automotive to industrial to medical. The RMI traction drive can be used in the electric vehicle market and precision applications. Offering benefits such as low backlash and no back driving, it set a new standard for “high efficiency”.
