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.

# Possibility to use a hollow shaft up to 70 mm diameter
# Low speed rotation, from 800 to 190 rpm depending on type
# Position signal with high resolution: up to 393612 points per revolution
# High accuracy resolver: +/- 1 arc min
# Optionally: sine / cosine or TTL encoder
Advantages
# No reducer
# No backlash
# High accuracy servo
# Suppression of maintenance
# Simplification of the mechanism
# Noise reduction

Black Bruin motors are at their best in situations where high torque is required and use of other transmission is not reasonable. Hydraulic transmission does not contain axles allowing the frame structure to provide e.g. higher ground clearance and sharper wheel turn angle.
Starting is soft and motion is smooth even at low speed. On the other hand, vehicles equipped with multi speed Black Bruin motors are capable of reaching top speed exceeding 70 km/h.
The motors are used e.g. as wheel hub motors for agricultural, forestry, road building and mining machines.
Black Bruin BB hydraulic motors
• light and compact design
• high torque
• broad speed range
• mechanical freewheeling
• excellent low-speed characteristics
