Extremely efficiency in a whole household of miniature brushless and slotless motors
March 04, 2021
Portescap has expanded its line of Extremely EC motors with new sizes, with motors now masking diameters from 16mm to 35mm.
Designed round Portescap’s proprietary U-coil know-how, these motors ship distinctive efficiency, minimal iron loss, improved effectivity and cooler operation.
The coil design makes use of straight copper turns to maximise magnetic discipline effectivity, with coil heads completely built-in into the compact motor design. The U-shaped coil optimizes motor dimension and maximizes usable copper quantity, with higher coil integrity. This permits the motors to ship as much as 30% extra torque than a identical dimension BLDC motor utilizing a traditional coil design, along with providing considerably decrease iron losses.
Recognizing that no electrical motor software requires the identical working traits, the Extremely EC household contains three distinct variations: the ECS line, the ECT line and the ECP line. Extremely ECS BLDC motors are optimized for prime velocity and acceleration in direct drive functions. Obtainable in diameters from 16mm to 35mm, these dynamic motors excel in functions the place responsiveness is a essential requirement. For instance, with a high-end magnetic circuit and minimal iron losses, a 22mm Extremely ECS 2-pole motor can ship powers of as much as 180W at 50,000rpm.
Plus, with superior vibration damping and built-in temperature monitoring, Extremely ECS motors meet the wants of functions that require cool, just about silent, and vibration-free operation. Over the entire vary of diameters, they ship energy as much as 330 W, torque as much as 193 mNm and speeds as much as 73,000 rpm.
When an software wants a motor optimized for prime torque within the smallest bundle, the Extremely ECT motor incorporates a multi-pole design to strategy the torque capabilities of a lot bigger motors. Steady torque might be as much as twice that of a traditional BLDC motor of the identical dimension, and even in comparison with related multi-pole motors, the ECT line gives 20-150% extra torque, with decrease velocity decrease underneath load.
Masking the gradual velocity vary sometimes used with gearboxes, ECT motors are simple to combine into gearboxes and encoders. They’re obtainable in diameters from 22 mm to 30 mm and provide energy as much as 244 W, torque as much as 225 mNm and velocity as much as 30,000 rpm.
The third mannequin within the Portescap Extremely EC household, Extremely ECP motors delicately stability velocity and torque functionality with price, opening up premium efficiency to a wider vary of BLDC motor functions. Appropriate with gearboxes and encoders, these cost-optimized motors can ship as much as 30% extra steady torque and 100% extra horsepower than competing motors of comparable dimension, whereas offering easy operation and lengthy life for which Portescap’s brushless and slotless motors are famend. Obtainable in diameters from 16mm to 22mm, Extremely ECP motors present energy as much as 120 W, torques as much as 50 mNm and speeds as much as 63,000 rpm.
Leveraging the flexibility of Portescap’s U-coil know-how, the three product households within the Extremely EC vary every spotlight a serious movement requirement, whether or not it is conventional BLDC traits, tremendous excessive torque, or very excessive velocity. The unique U-coil gives distinctive efficiency together with minimal iron loss, higher effectivity and cooler operation.
