The DCD1 servo drive is ideal for driving permanent magnet or separately excited wound-field DC servomotors equipped with a speed transducer, with voltages up to 260 V and maximum currents up to 50 A. The DCD1 features internal analogue circuits with an IGBT bridge and 4-quadrant operation with no deadband at zero speed: the motor...
"The PWM3D-001 digital servo drive is ideal for driving synchronous servomotors (permanent magnet brushless, with sinusoidal or trapezoidal commutation) and DC motors of any brand, equipped with a speed transducer, with voltages up to 480 V and maximum currents up to 118 A (rms). Fully digital, with an IGBT bridge and 4-quadrant operation with no...Continue reading
The 6ID digital servo drive from the D SERIES is the ideal solution for reliable control of permanent magnet or wound-field DC motors in unidirectional applications. Equipped with a proven 6-thyristor armature bridge, the 6ID operates in 2 quadrants. Its compact design houses both the thyristor bridge (up to 500 A) and the field bridge...
Alter direct current (DC) servomotors are the backbone of countless industrial applications requiring precise speed regulation and high starting torques. Designed to withstand prolonged duty cycles, these motors are available in two main configurations to suit every automation need: wound field and permanent magnet. Whether you are designing a new axis for a machine tool...Continue reading
The 12IRD digital servo drive (part of the D SERIES) is designed to power and control permanent magnet or wound-field DC motors with maximum precision. This bidirectional servo converter is equipped with a robust 12-thyristor armature bridge, allowing smooth and reliable operation in all 4 quadrants. For armature currents up to 500 A the thyristor...
The 6AXD digital servo drive is the flagship of the D SERIES for high-precision applications. Designed for DC motors, it is specifically suited to axis control in machine tools and in all industrial applications where deadband-free operation at zero speed is mandatory. It operates in all 4 quadrants (bidirectional) using a 6-thyristor armature bridge in...Continue reading
In this article I present the family of digital servo drives for d.c. motors with SCR bridge called “D SERIES“. Why is it called with this name? Our loyal customers will surely have used our 12IRC, 12SPC, 6AXC and 6IC drives at least once: they were born in the ’80s and were grouped in the...Continue reading
When a customer asks us what drive he should choose to replace a damaged one, the first question we ask is always the same: what kind of motor does the converter control? The motor data needed are: Type (e.g. DC, brushless, induction) Electrical specifications (e.g. armature current, supply voltage) Type of speed transducer mounted (e.g....Continue reading
