i need type of motor to move the 100kg object in vertical motion. it like to making hoist system. the motor need to lift up the object from ground to 2.5 meter above
You can calculate the power needed by using mental arithmetic. Let us assume that you want to complete the lifting operation in 5 seconds. Power = (mass x gravitational acceleration x height)/time Power = (100 x 10 x 2.5)/5 Power = 500 Watts This motor would have to drive a winch, through a gearbox and we could assume the efficiency to be 80%. Therefore, the motor would need an output power of 634 Watts. This is not enough information to allow you to design a motor-winch set. Take the advice given by the other answerer and buy a ready made winch.
A small commercially made electric hoist would be your most economical solution. Don
