I do it and understand the importance of the initial impact point having a definite effect on success of splitting the piece in the slot.
Electric motors are wound differently depending upon the usage. Some have very, very high torque as compared to engines, similarly some engines are designed for high torque. You can't compare the torque curves (not value, shape of the curves) of a BS 5 hp to a Johnny popper
Let's ask ourselves a question. GM has built diesel/electric railroad engines by the thousands for years. A single engine can pull 50 fully loaded box cars across the country with ease.
How much does the engine and 50 loaded boxcars weigh? Lots obviously.
How are you going to get all that moving? With lots of torque. Torque, defined as the twisting moment of inertia applied to an object.......prior to any movement measured in ft-lbs (US common measurement), distance of force measured in feet from point of use x weight applied from that distance measured in pounds. If/when it moves, it's HP...see below.
What has the most efficient torque for the package for the requirement? Series wound DC electric motors......apparently.
OK that's is the electrical part of the engine. What's the diesel for? Run the alternators that recharge the batteries that supply power to these high torque motors. Seems simple enough.
My personal experience is that the 5/3 rule is valid. It's all about torque. HP is nothing more than a measurement of rpm, torque, and a constant of proportionality. --------------- Butttttttttttt and a very big one at that. During the time the DC series wound motor is delivering it's torque, the armature isn't turning generating counter Electro Motive Force (CEMF). CEMF develops a back voltage which takes away from the initial voltage thus limiting the difference and the current required to operate the motor.
Result is what's called Locked Rotor Amps and can be 10x easily more than the normal (rated on the decal) running amps for the motor. So, you have to size your wiring accordingly. Since log splitting is repetitive, this 10x overload has to be factored into the wire run (size) to the motor. Engines have their advantages there.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
