Yes, the specifications data is a theoretical value, the motor power should be a little larger than required in specifications, but if the motor power is much more larger than required in specifications, it is not recommended. The screw jack or worm screw jack system components could be damaged if an large oversize motor is used. Travel limit switches control must be used for each end of travel to stop the motor. If using solid mechanical stops, screw jack components can be subject to shock load conditions and oversize motors can cause catastrophic failure of stops and other components.
