Heavy Case motors deliver smooth motion at a competitive cost
Rotalink's new range of Heavy Case (HC series) motors feature low-inertia skewed rotors with minimal detent torque and are suitable for use where smooth and accurate speed control and smooth acceleration are required at a competitive cost. The HC series complements Rotalink's broad range of standard brushed DC motors with a design that includes precision ball bearings and a heavier case construction offering added durability, improved overload protection and enhanced heat dissipation. These characteristics combine for increased duty and a motor life that is longer than average, making them suitable for applications in areas such as high-reliability automation machinery for industrial production and test, or medical devices and laboratory equipment.
The HC motors form an integral part of Rotalink's strategy that brings together a range of brushed and brushless DC and AC motor technologies with the company's innovative designs for gearbox, motor feedback and motion controls to realise highly competitive miniature power transmission systems of up to 28Nm output torque for rotary motion, and linear motion systems to more than 50N.
Rotalink's range includes planetary and spur gearboxes in a wide choice of output torque ratings featuring standard or ultra-polymer gears on sintered or ball bearings. For extremely high torque output in very compact designs, Rotalink manufactures an innovative range of ovoid-style gearboxes that combine spur and planetary gear stages using ultra-polymer materials technology that provide up to 28Nm peak torque in a gearbox case that measures just 95 x 60 x 31.5mm deep.
Rotalink also manufactures incremental and absolute encoders with space-saving designs that are easily adapted to applications for speed control and position feedback together with motion controls - such as the innovative Red Drive, a powerful DC motor drive that is available in brushed and brushless DC versions, with an easy-to use drag-and-drop flow chart programming language for motion control and combined TTL logic I/O.
The new Heavy Case motors are covered in Rotalink's new and revised full range catalogue, together with new rare earth and brushless DC motor ranges and several new gearbox lines.
