TK in his application. Remark: The liability of PHASE MOTION CONTROL is in all events limited to the functionality of the motor alone and is limited to its repair or replacement according to the rules agreed in the documente Condizioni Generali di vendita Phase Motion Control , www.phase.eu, which are implicitly accepted... -
Page 4: Electrical Risk
Drive start-up may produce sudden uncontrolled movement. Keep away from all moving parts to avoid injury! Do not connect motor to power supply other that specified by PHASE MOTION CONTROL. A defective power supply may damage the TK assembly. It is dangerous to interrupt earth or grounding connections. In no way must an earth wire be disconnected! Before servicing, make sure that the TK is not powered. -
Page 5: Transport And Storage Conditions
Transport and packaging The PHASE MOTION CONTROL standard package is designed to avoid transport damage. If any transport damage is observed upon reception of the goods, please inform immediately Phase Motion Control so that transport damages can be timely claimed or corrected. -
Page 6: Transportation
CAUTION: if the rotor must be shipped unassembled, i.e. not inside the stator, airline authorisation is required because of the stray field of the rotor. The use of the original iron box in which the rotor was supplied is recommended. As required, enquire with Phase Motion Control for the supply of a shielding box. -
Page 7: General Technical Information On Tk Frameless Motors
General technical information on TK frameless motors The TK series of frameless brushless motors provide the highest torque density available today for direct drive, high performance applications. Unlike traditional torque motors, TK units have both high torque and high speed capability and thus operate seamlessly both as spindle and table motors. -

To ensure adequate servo performance in direct drive high accuracy, high stiffness applications such as indexing and rotary tables in NC machine tools, the sensor must be sinusoidal so that the drive Phase Motion Control... -
Page 9: Spindle Motors For Mills And Lathes
Spindle motors for mills and high speed machining centers • Wire grid manufacturing Tube motors, small diameter, for multiple spindle units Typical applications: • High speed/power motors where lateral (pitch) space is limited • Multiple drilling heads • Swiss type lathes Phase Motion Control... -
Page 10: Selection Guidelines
It can be observed that above the “knee speed” i.e. the speed of transition between constant torque and constant power operation, the motor temperature becomes progressively independent of motor load. Phase Motion Control... - Page 11 In the Phase TK technology, there is no fundamental physical difference between torque motors and spindle motors; they have the same smoothness and high bandwidth necessary for direct drive indexing and contouring operation, so that milling and turning operations on the same motor are now possible.
- Page 12 As a standard the air-gap is in the order of 1 mm, radial, and this generally enables designs in which the motor rides on the machine supports without need of separate bearings. Phase Motion Control...

Page 13: Motor Morphology And Protections
Motor morphology and protections PHASE MOTION CONTROL TK brushless motors are the technical solution with the highest torque density currently available and are designed for high performance motion control. Tk motors are frameless and are supplied as separate stator and rotor units for integration into the final equipment. - Page 14 DV/dt typical of 600 Vdc servo drive application; the windings are equipped with thermal sensors and thermal protectors as detailed later in this document. The star point of the winding is also generally available for filtering purposes. Phase Motion Control...

The DC-Bus setting of the power amplifier is only 600 Vdc but the instantaneous voltage can reach a value as high as 1600 V. The insulation system cannot withstand this high voltage in long term operation. Phase Motion Control... - Page 20 To limit such voltage transients, P Phase supplies with each motor with such characte eristics a tuned anti resonance filter (snubber) which must be assembled within 5 m of the motors, b between the motor star terminal (white wire) and m machine ground.

Page 22: Rotor
Contact PHASE MOTION CONTROL if rotor is damaged. On request, rotors can be supplied with dual diameter and connection hole for hydraulic disassembly Mounting of the rotor inside the stator Important warning: Avoid contact or close proximity of the bearings or parts thereof with the rotor magnets. - Page 23 (Remark: on request Phase can supply mylar shims together with the motor). 2) Immediately prior to rotor instertion in the stator, peel the protective tape from the surface of the sleeve, check for cleanliness of the rotor surface; if any metallic part is attracted by the rotor, clean the surface peeling with a adhesive tape.
