Muscle recruitment
There is no 'multi motor unit' to be different from a single motor unit!A single motor unit is all the muscle fibers controlled by a single motor neuron.Multiple motor unit summation is when a smooth and steady increase in muscle tension is produced by increasing the number of active single motor units.Notice that what's being described is not something having to do with a some non-existent thing called a 'multi motor unit', but rather is a summation of many active singlemotor units.
The response of a motor unit to a single action potential of its motor neuron is called a muscle twitch. This involves the contraction of all the muscle fibers within the motor unit in response to the stimulation from the motor neuron.
Peripheral adaptations can increase the number of action potentials that reach the CNS by enhancing sensory receptor sensitivity, increasing nerve conduction velocity, and improving the recruitment of motor units. These adaptations contribute to better coordination and control of movements.
A motor neuron and all of the skeletal muscle cells it stimulates together form a motor unit. The motor neuron sends signals to the muscle cells to contract and produce movement. Each motor unit typically controls multiple muscle cells to allow for coordinated and efficient movement.
The site where a motor neuron and muscle cell meet is called the neuromuscular junction. This is where the motor neuron releases neurotransmitters that signal the muscle cell to contract.

The number of batteries can affect the speed of a motor. Increasing the number of batteries can provide more power to the motor, potentially increasing its speed. However, there may be limitations based on the motor's design and the capacity of the batteries.
reactive power depends on motor winding losses and the reason for increasing of temperature. At running condition the motor power reduces by copper loss.

As the number of poles (P) increases, the speed of an induction motor (N) decreases. As seen by the formula: N=(120*f)/P
Recruitment affects the number of motor units activated in a muscle, while frequency of stimulation affects the force generated by those motor units. Increasing recruitment leads to more muscle fibers being recruited, increasing force production, while increasing frequency of stimulation produces stronger muscle contractions by increasing the rate at which motor units are activated.
microtubules
keep the same winding configuration or number of poles increase the diameter of the rotor and stator
The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.
To increase power of the motor, by increasing airflow thru the motor(higher volumetric effiecency) when needed.
Let see an example. The active power absorbed by an AC motor is used to produce mechanical power delivered on the output shaft. If the mechanical power is negative (the motor is pushed to work as a brake) the active power 'absorbed' is also negative. The motor converts the mechanical power in active electrical power delivered in the electrical network. Any AC generator is supplied with negative active power, or it deliver to the network positive active power.
Because it steps the shaft by a fixed number of degrees each time it is actuated.
