Product catalog summary

Introduction to Direct-Drive Technology
Direct-Drive technology utilizes torque motors in rotary axes, eliminating mechanical transmission components like gearboxes. This enhances reliability and precision, with the motor's electromagnetic design influencing speed, torque, and power. Electronic regulation and feedback systems are crucial for motion quality.

Advantages of Direct-Drive Technology
Direct-Drive systems reduce mechanical complexity, friction, and wear by eliminating gearboxes, leading to improved performance, energy efficiency, and cost savings.

Electronic Regulation and System Quality
Electronic regulation in Direct-Drive systems replaces mechanical functions, enhancing performance and precision, particularly in machine tool applications. The system's quality depends on its ability to manage mechanical resonance and achieve high resolution and accuracy.

Dynamic Rigidity and Torque Disturbances
Direct-Drive systems provide dynamic rigidity through active and inertial rigidity, allowing real-time response to torque disturbances, essential for high-speed cutting applications.

Operation Safety and Quality Standards
Technai ensures high manufacturing standards, focusing on electric insulation and winding protection. Advanced testing procedures ensure motor quality and longevity.

TORQUE MOTORS MK-CI SERIES | INTRODUCTION 2. INTRODUCTION TO THE DIRECT-DRIVE TECHNOLOGY “Torque motors” are applied to rotary axes as “Linear motors” are applied to straight axes. Both are the expression of the technology named Direct-Drive. The Direct-Drive principle is quite simple: the electric servomotor generates the mechanical energy which is used for driving the payload. The fundamental difference when compared to conventional systems is the absence of any mechanical means for motion transmission, e.g., gearboxes, couplings or drive belts. Speed, Torque and Power of the Direct-Drive systems...

5. OPERATION SAFETY AND QUALITY STANDARDS OF TECHNAI TORQUE MOTORS All motors manufactured by TECHNAI Team correspond to high standards of execution, where particular care has been given to the electric insulation and the winding protection. Each single motor is subject to accurate tests and measuring steps during the entire manufacturing process (slot insulation, arrangement of windings, electric connections, impregnation and final encapsulation using epoxy resin). The entire manufacturing process is kept under control in each single step. During each acceptance test a document will be issued...

TORQUE MOTORS MK-CI SERIES | INTRODUCTION This allows to evaluate the quality of the insulating materials between the winding “phases”. The insulating materials may present faults such as different types of micro-cavities caused during the manufacturing process and also metal splinters. These faults may cause local concentrations in the electric field thus exceeding the limit value of the field and causing consequently the phenomenon of Partial Discharges. The term “Partial Discharge” depends on the fact that this phenomenon occurs on microscopic level thus involving only a part of the existing...

THERMAL LOSSES [watt] 6. THERMAL PROTECTION AND THERMAL PROBE FITTED INTO THE 9000 WINDINGS CEff Cnom 6000 The thermal protection is the only strategy valid for protecting the motor! The DIRECT DRIVE motor from TECHNAI is provided with two types of thermal probe. 3500 watt The PTC thermal3000 probe is the predominant one to be used for protecting the motor against overtemperatures. If the PTC temperature probe intervenes, the drive must be rapidly disabled so that the converter of the drive does not continue supplying0 any current to the stator. This condition of thermal load is caused by electric...
