Product Solutions

Brush DC Motors
Brush DC Motors pack a powerful punch in a compact size, offering high power density and a range of benefits including low friction, low starting voltages, minimal iron losses, and excellent speed-to-torque performance.

Brushless DC Motors
Brushless DC Motors from Portescap represent the pinnacle of high-performance motor technology, available in both slotted and slotless designs. These brushless DC motors deliver remarkable torque and speed, along with superior efficiency, and come in a range of package sizes to suit diverse needs.

DC Torque Motors
DC Torque Motors from our range are low-voltage DC direct drive motors engineered to produce high torque at very low speeds. They are an excellent fit for applications that require simple control, exceptionally smooth motion, and high rate and position accuracy, all while minimizing size, weight, power, and response time. These motors act as servo actuators that can be directly coupled to the driven load, utilizing a permanent magnet field and a wound armature to efficiently convert electrical power into torque.

Flat Motors
Our range of Flat Motors excel in space-constrained, high-performance applications, thanks to their compact, flat design. These motors are ideal for scenarios where a higher load carrying capacity is needed without sacrificing speed, or where maximum power per dollar is a priority.

TBM2G Series Frameless Motors
TBM2G Series Frameless Motors represent the next generation of brushless motors, offering high torque density in a compact, lightweight package. Standard sizing ensures compatibility with harmonic gearing, and the scalable design supports global production needs.

TBM Series Frameless Motors
TBM Series Frameless Motors offer direct drive capabilities, designed to be integrated directly into your system's mechanical structure. This minimizes weight, size, and inertia without compromising performance.

RBE Series Framelss Motors
RBE Series Frameless Motors offer a pancake-style design that provides high torque at low speeds, eliminating the need for shafts, bearings, endbells, and couplings. This reduces volume, weight, and complexity when integrated directly with the load.

Servo Motors
Our brushless servo motors provide an exceptional torque-to-inertia ratio across a wide range of speeds, including high-speed capabilities up to 8,000 rpm for standard designs.

Stepper Motors
Our range of Flat Motors excel in space-constrained, high-performance applications, thanks to their compact, flat design. These motors are ideal for scenarios where a higher load carrying capacity is needed without sacrificing speed, or where maximum power per dollar is a priority.
