The 30mm diameter ironless-rotor DC motors from Portescap's 30GT range, available through Delta Line Europe, boats a continuous power rating of no less than 70W. These tiny motors, which are just 62mm long, combine their high power/size ratio with extended operating life, thanks to the use of high-quality graphite-copper brushgear and precision ball bearings.

Portescap 30GT motors are currently offered, as standard, for use on 24 or 48V supplies. The typical maximum operating speed for all models is 11,000rev/min, with 24V units capable of developing continuous torques of up to 83mNm, a figure which rises to 104mNm for 48V motors. All 30GT motors can operate well in excess of their rated torque for short periods.

Benefits of the Portescap ironless technology used in these motors include low friction, low starting voltage, no iron losses, good thermal dissipation and a linear torque-speed characteristic. All of these factors facilitate the use of the units in high-performance drive and servo systems. In addition, their high efficiency means that they are also excellent for applications in battery-powered equipment.

To complement its small but powerful 30GT ironless-rotor motors, Portescap offers an extensive range of standard and custom miniature gearboxes. Designed for simple and quick attachment to the motor, these gearboxes are available in both spur and planetary versions, with a wide range of reduction ratios.
