Parker: Torque Motor Kit (K044 Series)
Frameless Brushless Torque Motors
The frameless Kit Motors STK and K - Series are the ideal solution for machine designs that require high performance in small spaces. Kit Motors allow for direct integration with a mechanical transmission device, eliminating parts that add size, weight and complexity. Use of Frameless Kit Motors results in a smaller, more reliable motor package. The STK and K - Series support applications need a large-diameter hollow shaft with ring-type technology.
Direct drive motors as STK and K - Series motors provide higher dynamic stiffness by eliminating the compliance of shaft attachments. Direct drive motor construction gives equipment designers the advantages of lowered costs, increased reliability and improved performance. Frameless Kit Motors are the most cost effective direct drive motor solutions available. Kit motors save space in applications because the couplings, motor mounting brackets and extra bearings you would find in coupled drive construction are eliminated.
Continuous torque from 0.044 Nm to 2700 Nm with natural convection (according to size), and up to 6100 Nm with fluid cooling.
A wide range of external diameters from 32 mm to 800 mm.
Internal diameters from 15 mm to 630 mm.
Various windings available from 30 min-1 to 1500 min-1 according to size.
Electromagnetic and thermal optimisation has permitted high torque to-weight ratios to be achieved with natural convection and even higher with fluid cooling.
The Parker STK and K - Series range of frameless motors addresses very demanding industrial applications, not only in terms of performance (dynamic performance, torque capability and precise rotation at low speed) but also in terms of cost. Particular attention has therefore been paid in the design to the combination of technical and economic optimisation. Parker also addresses direct drive applications up to 30 kW in natural convection at speeds up to 1500 min-1 for STK and up to 50 000 min-1 for K - Series.
The various speed ratings are achieved by having a range of available windings.
The Frameless Kit motors are ideal solutions for machine designs that require high performance in small spaces. The kit motor approach allows for direct integration with a mechanical transmission device, eliminating parts that add size and complexity. The use of frameless motors results in a smaller, more reliable motor package.
Pre-installed integral commutation board is pre-aligned for easy assembly.
Rare earth magnets provide high flux in a small volume and high resistance to thermal demagnetizing.
Machined grooves securely lock magnets to rotor and ensure optimized radial location.
Class H insulation for high temperature operation (up to 155°C) meeting UL approved requirements.
High density copper winding for low thermal resistance and consistent performance across all motors.
Minimized end turns to maximize performance and minimize motor size.
Skewed laminations with odd slot counts reduce cogging for precise rotary motion with drastically reduced torque ripple even at low speeds.
Optimized torque-to-size ratio hand inserted to obtain highest slot fill possible maximizing ampere-turns.
