KBM: HIGHLY DYNAMIC FRAMELESS TORQUE MOTORS

The frameless kit motor of the KBM™ series is Kollmorgen's latest innovation in rotary direct drives. The KBM kit motor offers engineers in mechanical and plant engineering a wide range of solutions to realize applications with a maximum of flexibility, power density, dynamics and service life. The kit motor of the KBM series is also extremely easy to fit and install. Hall effect sensors are optionally available ex works. The KBM direct drives are available in every size with several winding variants; the optimized insulation properties allow the use in a wide voltage range up to 680Vdc.

With eight flange sizes from 40 to 260mm and several overall lengths each, an enormous spectrum of applications with holding torques from 0.18 Nm to 180 Nm can be covered. The sizes are selected in such a way that the torque ranges of two adjacent flange sizes overlap and thus an ideal ratio between load and rotor inertia can be found.

 

For the KBM frameless torque motor series, a clever combination of standard elements was chosen, resulting in short delivery times and an excellent price-performance ratio.

 

The most important features of KBM frameless torque motors are:

  • 14 sizes (60mm to 782mm OD), each with 3 or 4 different lengths
  • continuous holding torque from 0.5 Nm to 3,500 Nm
  • potted stator winding
  • max. internal winding temperature 155°C
  • thermal sensor in the winding (PTC)
  • bonded rotor magnets
  • customer-specific frameless torque motor versions possible

TBM: Frameless direct drive torque motors for low voltages 24Vdc / 48Vdc / 100Vdc

Kollmorgen's TBM series of frameless torque motors are rotary direct drives without integral bearings, are suitable for low operating voltages of 24Vdc, 48Vdc up to 120Vdc and are integrated directly into the machine; mechanically they use the machine's bearings and the position sensor is not part of the kit torque motor. The standard torque motors offered are characterized by high performance in a compact design with minimum weight and moment of inertia; the standard versions provide a good basis, but can be customized to find the right rotary direct drive for your application. The frameless kit torque motors of the TBM series are used where high performance is required in a small and compact high torque motor with minimum weight and moment of inertia.

 

The most important features of the TBM torque motor series are:

  • several sizes from 60 to 129mm outer diameter
  • optimized standard windings for 24Vdc, 48Vdc, 96Vdc
  • low cogging torque
  • corrosion-resistant stainless steel rotors
  • bandaged rotors
  • nameplate of the frameless torque motor with laser marking
  • RoHS compliant
  • CE compliant (at rated voltage)
  • optional: customer-specific windings, digital Hall Effect sensors with memory function

CARTRIDGE DDR: HOUSED TORQUE MOTORS WITHOUT INTEGRAL BEARING

The torque motors of the CARTRIDGE DDR® series from our partner Kollmorgen are rotary direct drive high pole count servo motors. They combine the advantages of frameless kit motors with those of a finished motor, because the motor is pre-assembled in a housing and the high-resolution encoder is also already installed and adjusted at the factory - but the motor does not have its own bearing. The CARTRIDGE DDR® thus represents a completely new class of direct drive rotary torque motors.

For the customer, this results in extremely simple integration without the usual risk in encoder selection and design; in addition, Cartridge DDR offers defined and measured performance data; a sophisticated packaging concept ensures extremely simple installation in the machine. However, mechanical overdetermination with regard to the bearings is avoided. Not only do they combine the performance advantages of frameless direct drive motors with the simple mounting of housed motors, but they are also available at a significantly lower price than conventional direct drive torque motors and also save money by eliminating mechanical components. Conventional servo systems typically require a number of mechanical components for power transmission, which not only limit the performance and reliability of these systems, but also drive up operating costs. The CARTRIDGE DDR torque motors, on the other hand, do not require mechanical components for power transmission.

The CARTRIDGE DDR® torque motors are UL listed and can be used for applications worldwide.

 

The advantages of the CARTRIDGE DDR® torque motors are obvious:

  • simplified installation (5 minutes) - simply install the motor and connect the cables
  • increased machine operating times due to maintenance-free operation
  • up to 20 dB less noise due to the omission of the power transmission mechanism
  • up to 50 times improved accuracy
  • the direct coupling to the load makes maintenance of gears, belts or pulleys unnecessary: no maintenance - no operating costs
  • low cogging ensures smooth running at low speed
  • higher torque density than conventional direct drive servo motors due to unique electromagnetic design
  • improved system response due to eliminated backlash and compatibility
  • easy installation and commissioning of the system thanks to preconfigured amplifiers and feedback units

The most important features of CARTRIDGE DDR® torque motors are:

  • 5 flange sizes: 108mm, 138mm, 188mm, 246mm and 350mm
  • several overall lengths of each flange size
  • continuous torque from 4.6Nm to 510Nm
  • peak torque from 11Nm to 1.017Nm
  • speeds up to 1,500rpm
  • sine encoder for absolute position with a maximum resolution of 2,097,152 steps per revolution
  • overtemperature protection by built-in thermistor

PDDR: HOUSED TORQUE MOTORS WITH PRECISION BEARINGS AS ROTARY TABLES WITH HOLLOW SHAFT

The torque motors of the PDDR series from our partner PBA are rotary direct drive servo motors, completely installed in the housing with a high-resolution encoder system and precise bearings - basically they are direct drive rotary tables with a thru bore (hollow shaft).

 

A special magnetic design results in high torques with low detent torque (cogging), making PDDR motors suitable for dynamic applications with high synchronisation requirements.

 

The advantages of the PDDR series direct drive rotary tables are:

  • low cogging torque ensures smooth running at high and low speed
  • very good controllability even at low speeds
  • high repeatability and accuracy due to no gearing backlash, slippage or coupling compliance errors
  • compact design due to high torque density
  • excellent dynamic behaviour
  • easy integration and installation
  • high service live with no maintenance

 

The most important features of PDDR torque motors are:

  • 6 sizes with diameters of 110mm, 150mm, 160mm, 240mm and 300mm
  • several overall lengths of each flange size
  • hollow shaft (through bore)
  • various mounting options
  • continuous torque from 2Nm to 400Nm
  • peak torque from 6Nm to 1,090Nm
  • sine encoder with optional interpolation (TTL encoder)
  • overtemperature protection by built-in thermistor
  • Hall effect sensors

The KinetiMax external rotor torque motors are available in 6 sizes, each with 3 different lengths and windings to ensure maximum flexibility and to suit your application. High torque and low cogging make the direct drives suitable for use in robotic applications, AGVs or tools.

 

The key features of KinetiMax HPD external rotor torque motors are:

  • 6 sizes with diameters from 62mm to 125mm
  • in each size 3 lengths and 3 winding options
  • torque from 0.24Nm to 6.7Nm
  • power of up to 1,171W
  • low cogging torque
