Hence it is called a variable reluctance stepper motor. In this motor, the direction of the motor is independent of the direction of the current flow in the windings. Permanent Magnet (PM) stepper motor. Here the rotor is permanently magnetized.he hybrid stepper motor, as the name suggest is a motor designed to provide better efficiency by combining the pros of both the permanent magnet stepper motor and variable reluctance stepper motor. The VR and PM stepper motors are the most common type of stepper motors.
Entrez Gene Summary for COMT Gene. Catechol-O-methyltransferase catalyzes the transfer of a methyl group from S-adenosylmethionine to catecholamines, including the neurotransmitters dopamine, epinephrine, and norepinephrine. This O-methylation results in one of the major degradative pathways of the catecholamine transmitters.
CMT is a genetic disease-it is an inherited disease. It is caused by inherited mutated genes that are involved in producing substances (proteins) which affect either the axon or myelin sheath of the peripheral nerve.In all cases of CMT, several mutated genes are involved in causing the condition (not just one).s CMT is a hereditary disease, people who have close family members with CMT have a higher risk of developing the condition themselves. Understanding how the periphery nerves function is important if you want to have a better appreciation of what causes CMT.
