Benshaw’s MX2 SEP Synchronous Controller is a microprocessor-based, closed-loop current controller package for brush type or brushless synchronous electric motors. The MX2 SEP controller continually regulates the amount of field current being delivered to the motor, which protects the motor from overheating due to excess field current.
Benshaw’s MX2 SEP controller offers programmable current and power factor regulation modes. Our power factor regulation mode utilizes advanced MX2 or MX3 microprocessor-based controls for its metering and protection capabilities.
Synchronous motors function as an induction motor during start-up. Once the motor approaches full synchronous speed, Benshaw’s RediStart DC exciter induces a constant polarity to the rotor, causing the motor to lock into sync. Because the rotor’s field is constant, and separately excited, there is no slip required to produce torque, as with an induction motor, allowing the motor to run at synchronous speed.
Benshaw synchronous packages can be incorporated into solid state starters, full voltage starters, or supplied as a separate stand alone package. The SEP (Synchronous Exciter Package) can be supplied for brush type and brushless exciters.
Solid State Starter with SEP
The Benshaw synchronous solid state starter package consists of a RediStart series solid state starter connected to the stator to provide a smooth stepless acceleration, and the SEP section that is connected to the rotor, in conjunction with the discharge resistor to provide automatic synchronization. This can be supplied for brush type, and brushless exciters.
Full Voltage Starter with SEP
The Benshaw synchronous full voltage starter package consists of a contactor starter system that is connected to the stator, and the SEP section that is connected to rotor, in conjunction with the discharge resistor to provide automatic synchronization. This can be supplied for brush type, and brushless exciters.
Stand Alone SEP
The Benshaw stand alone Synchronous Excitation Package can be connected to the rotor section in conjunction with a discharge resistor, and incorporated into an existing starting system to provide automatic synchronization of the three phase AC synchronous motor.
Benshaw solid state controls reflect 30 years of valuable experience in the design, production and installation of high performance, mission critical motor controls for heavy duty continuous process applications. Our next generation synchronous controllers for synchronous motors and generators are a source of pride for the entire company.
