The TORQUECHAMPION® direct drive system is the new highly dynamic drive system from LTi DRiVES for precise, fast and maintenance-free positioning.
* Its short length and lack of gearing means it takes up a minimal amount of space.
* The peak torque of the MIC motor is available up to the maximum speed, making positioning faster.
* The hollow shaft permits simple feed-through of cables, hoses or laser beams through the motor.
* The integrated measurement system with 8,388,608 increments per revolution and single-turn absolute information means no reference running is required.
* The MTC motor is an external-rotor motor. It can be coupled with a high degree of torsional rigidity without gearing directly to the mechanism. This means it has no gear play and suffers no wear, needs to maintenance and offers very high drive dynamics.

Application - Reversible power drive for special purpose m/cs, actuators, pumps, label printing machines, medical and optical equipment, vending machines etc.
Design - The MTR9a/9b/9c/9d reversing synchronous motor with parmanent magnet rotor
The rotating field is produced with a phase-shift capacitor and doublestator
with coils thus ensuring extremely quiet running and smooth operation. Long life is ensured by the ball bearings. Compared to normal parmanent magnet synchronous motor that operates on tin can principle, these motors are more
efficient. At same time the temperature rise is significantly higher
in this motor. MTR9a/9b/9c/9d is operated with single-phase AC current. The same motor version can be used at 50Hz and 60Hz.

Design - MT6 is a unidirectional synchronous motor. The direction of the motor is either cw or ccw which is fixed with help of reversing stopper while manufacturing. This non reversing device also guarantees at all times starting in the desired direction with high starting torque. The motor consists of a cylindrical sheet iron stator which form the poles. Mounted on the hardened and
highly polished rotor shaft is a high coercitivity sintered magnet ring around whose circumference 10 poles of alternate polarity are disposed, Special version of motor without the non reversing device is also available. In this case the motor can start in any direction. Motor can be priovided with screw
clip for fixing.

PTM series synchronous motors range in diameter from 25mm to 55mm, and are low speed permanent magnet motors ideal for timing applications. The single direction (shaded pole design) and reverse direction (phase-shift by capacitor) motors allow automatic self-starting and dynamic braking. With internal impedance protection, the shaft can be stalled continuously without the danger of burning the coils. A variety of plastic and metal gear heads on all models of PTM series synchronous motors are available to meet the requirements of most applications.
