With an experience of over 200 years and above, Rexroth Bosch group continues to provide engineering solutions for over 500,000 customers all specially designed for moving, controlling as well as driving applications.  The innovation of the new MK090B-035-KP1-KN synchronous motors comes with new developments that are used in driven tools.  High-quality materials have been used thus achieving continuous power even at very high speeds.

The MK090B-035-KP1-KN synchronous motors are integrated with natural and surface cooling techniques to enhance efficiency while cooling.  The natural cooling ranges from 100 K to 60 K while that of the surface technique is 60K/100k.

 The electrical parameters of the MK090B-035-KP1-KN synchronous motors enhance efficiency and cost-effectiveness.  The continuous torque at a standstill is 18, 0 Nm for the surface cooling technique while that of the natural cooling is 12, 0-13, 5 Nm. The continuous current at standstill for the surface cooling is 16, 5 A while that of the natural range from 11, 0 to 12, 5 A.  Both the natural and the surface cooling techniques have a  peak current of 49,5 A. while the torque constant for both stands at 1,22 Nm/A.  The voltage constant for both techniques is 111 V/1000 min-1.

The mechanical parameters of the MK090B-035-KP1-KN synchronous motors are critical for the safety and maintenance of the motors. The motor ’s rotor inertia is 43,0 X 10-4 Kg/m2 while the motor mass is 14,0 Kg. Whether using the natural of the surface cooling technique, the minimum strand cross-section and the thermal time constant is the same 1 mm2 and 60 min respectively.  The maximum speed for MK090B-035-KP1-KN synchronous motors using either the natural or the surface cooling is 5000 min-1.  The MK090B-035-KP1-KN synchronous motors fall within the protection category of IP65 and an insulation class F according to DIN VDE 0530 part 1.
