Simple circuit to power a 4HP 180 V DC motor
Not Feasible

This linear method dissipates 50% of 3kW Motor power at maximum power transfer.

Any attempt to apply full voltage on a stationary motor also only sees the motor winding DCR which results in up to 10x surge current initially  ( or a fried resistor)

You need to buy a Motor Speed controller that matches your need to accelerate as a fraction of max acceleration which is 30kW initial power!!   Some physics skills needed here.
