Brush DC Motors

Athlonix 22DCP Brush DC Motors deliver speed-to-torque performance in a cost-efficient package

Portescap introduces the next generation of AthlonixTM high power density brush DC motors. Athlonix DCP motors offer an optimized price-to-performance solution ideal for a broad spectrum of applications. Available in a 22mm diameter, the new 22DCP motor will feature an energy efficient coreless design with an optimized self-supporting coil and magnetic circuit, which ensures optimum price to performance ratio is delivered.

Brushed DC Motor Driver with Internal Current Sense

The DRV8871 is a brushed-DC motor driver for printers, appliances, industrial equipment, and other small machines. Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETs that can control motors bi-directionally with up to 3.6-A peak current. The inputs can be pulse-width modulated (PWM) to control motor speed, using a choice of current-decay modes. Setting both inputs low enters a low-power sleep mode.

The DRV8871 has advanced current regulation circuitry that does not use an analog voltage reference or external sense resistor. This novel solution uses a standard low-cost, low-power resistor to set the current threshold. The ability to limit current to a known level can significantly reduce the system power requirements and bulk capacitance needed to maintain stable voltage, especially for motor start-up and stall conditions.

Brushless slotless motor

Portescap introduces the newest addition to our Ultra EC™ mini motor platform, the 22ECT brushless motor, designed specifically to deliver ultra high torque in a compact size. With the unique coil technology and a patent pending multipolar rotor design, the 22ECT has been developed to be one of the most advanced and highest performing brushless slotless motors in its class. The 22ECT is specifically optimized for high continuous torque at low to medium speeds, maximizing power between 10 K and 20 K rpm. These motors are capable of delivering 2 times higher continuous torque than comparable BLDC motors of same size over the entire low speed range when used with gears.
