Torque Motors

发布时间:2017-07-07 10:43:07 人气:

  Direct Drive technology has recently

  become more and more commonplace

  in machine and factory automation.

  Parker‘s Electromechanical Division

  has been well known for many

  years as a specialist in direct drive

  technology. Parker offers various

  kinds of torque motor, in „ready to

  run“ and kit form, as well as linear

  motors. These motors are ideal

  for solutions in printing machines,

  bending machines or machine tools

  which require extremely smooth

  rotation, especially at very low speed,

  and very high accuracy. Frequently

  there is also a requirement for a

  hollow shaft.

  Designed with the aim of addressing

  new industrial needs, Parker has

  developed the ST range of low inertia

  motors for Direct Drive providing

  acceleration rates up to 20 000rad/s².

  The ST range is available in three

  diameters, 145mm, 190mm and

  300mm, with either hollow or solid

  shafts of 60mm till 75mm diameter

  respectively. Rated torques range

  from 15Nm to 235Nm in natural

  convection, with peak torques from

  55Nm to 1161Nm. The motors can

  reach rated speeds of 200pm till

  1 500rpm according to winding

  type and provide exceptional speed

  regulation at low speed.

  The 145mm, 190mm and 300mm ST

  ranges offer outstanding performance

  with a continuous torque-to-weight

  ratio up to 3.7Nm/kg and a peak torque-

  to-weight ratio up to18Nm/kg.

  Parker has also expanded its product

  portfolio with a new range of Direct

  Drive frameless motors.

  Complementary to its ST range, these

  kit motors (stator + rotor) are designed

  to be integrated within machine tools

  such as rotary tables and grinding

  heads. These applications frequently

  require a large-diameter hollow shaft

  as well as high accuracy and speed

  regulation.

  The new STK frameless motor range

  offers outstanding rated torque

  from 15Nm to 2 700Nm in natural

  convection, and can reach 6 100Nm

  using fluid cooling. The peak torque

  is 3 times higher than the rated torque

  (up to 9 000Nm) and is available up

  to the rated speed.

  The large-diameter hollow shaft

  provides an internal clearance

  between 56mm and 630mm.

  Parker Direct Drive motors have

  been designed and industrialised

  with the aim of ensuring excellent

  performance as well as acceptable

  cost for users.

  Compax3

  -Servo Drives of the Third Generation-

  Modern digital control technology aids

  the realisation of highly productive and

  flexible automation solutions. It forms

  the basis of a stable control system

  and, most importantly, the precise

  positioning of linear actuators or other

  direct drive technologies. Without

  requiring any additional options,

  Compax3 supports diverse motor

  technologies including synchronous

  servo motors, linear servo motors and

  even torque motors.

  Due to its inherently modular structure,

  the Compax3 intelligent servo drive

  can be employed in a wide range of

  industrial applications. Based on a

  standard version of the drive, Parker

  Hannifin is able to offer a large number

  of additional PLC- and advanced

  technology functions for the

  Compax3.
