Motor applications are on the rise, and the dramatic reduction in the cost of power MOSFET devices over the last decade, particularly MOSFET gate-drive ICs for low voltage (less than 100 volts) ...

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed ...

Voltage unbalance can be a common steady-state power quality problem that is harmful to 3-phase electric motors. The condition can cause overheating and insulation damage. The cost of damage to motors ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...
