The planetary and coaxial gear configuration design can absorb the high starting torque
(240 percent] produced by the high torque design "C" electric motor that is able to start the conveyor under full load conditions.

The selection of airfoil design is based on the performance of the Cl/Cd ratio although both have low starting torque
Initially Motor starting torque
165Nm and finally settled the motor torque value of 75Nm.
Various supplementary design parameters were given from ICE technical data, including the starting torque
that ERPMSM had to overcome.
Similar to these applications, apron and belt feeders operate in harsh environments, where they face both high starting torque
and frequent load spikes.
A high guideway accuracy combined with high rigidity, a low starting torque
, and a constant continuous torque.
Despite high starting torque
and wide constant power operation region of PMSMs, the use of a single-speed gearbox requires a motor with high torque to achieve acceptable levels of acceleration and gradeability.
Realistically, in the presliding process of the torque motor, the input voltage signal is less than the starting torque
of torque motor and changes only gradually; thus it is reasonable to disregard the acceleration of motor rotor and the change rate of LuGre model internal state.
Thanks to integrated bearings in hybrid technology the starting torque
and frictional torque in operating speed are even lower than those of the air bearing separator rollers, which are known for low friction.
The mill is powered by a 150 hp, two-speed, high starting torque
Weg's SSW06 soft starters reduce starting torque
in the powertrain by controlling the voltage delivered to the motor.
