In today's pursuit of complex soft start and variable frequency control, there is a tool that always occupies a cornerstone position in a large number of standard applications with its incomparable structure, reliability, and economic value - that is SPX's customized Full Voltage Magnetic Motor Starter. It abandons all intermediate links, like the most loyal and reliable switch, injecting grid energy directly and instantly into the motor, completing the purest kinetic energy conversion. Our full voltage magnetic motor starter is the modern engineering crystallization of this classic logic, providing the strongest and most efficient first driving force for devices that do not require "gentle" starting.
The system consists only of isolation switches, fuses (or circuit breakers), electromagnetic contactors, and overload protectors, with the minimum number of components and clear logic. This means fewer failure points, simpler maintenance, and higher overall system reliability.
At the moment when the contactor is engaged, the motor starts at full torque without any timing or logic delay, with the fastest response speed.
Compared to star delta, autotransformer, or frequency converter solutions, the Full Voltage Magnetic Motor Starter has the lowest component cost, installation cost, and cabinet space occupation.
After startup, the motor operates at full voltage without any inherent losses of voltage reducing devices, with an operating efficiency of 100%.
The start command causes the Full Voltage Magnetic Motor Starter coil to be energized, the main contacts to close, and the three-phase voltage of the power grid is directly and fully applied to the motor terminals. The motor starts and accelerates to its rated speed according to its inherent characteristics.
Starting current: usually 6-8 times the rated current, it is necessary to evaluate whether the capacity of the power grid or transformer can withstand it, in order to avoid causing excessive voltage drops and affecting other equipment on the same power grid.
Starting torque: also a multiple of the rated torque, it is necessary to confirm whether the mechanical transmission system (such as gears, belts, loads) can withstand the mechanical impact at this moment.
Drive small water pumps, fans, and compressors (usually referring to equipment with a power within the allowable direct starting range of the power grid, such as 7.5kW, 11kW, etc., depending on local power grid regulations).
Starting devices such as flywheels and large inertia rollers, the Full Voltage Magnetic Motor Starter with high starting torque helps to quickly overcome inertia.
Full Voltage Magnetic Motor Starter is widely used in highly standardized equipment such as machine tools, conveyors, mixers, etc., and its mechanical design has considered direct starting impact.
In systems with sufficient power capacity margin, Full Voltage Magnetic Motor Starter is used to control non core equipment to reduce overall costs.
