Cost Optimized 40mm Brushless DC Slotless Motors
Portescap is introducing a new cost-optimized brushless DC slotless motors in 40mm diameter. This 4-pole motor offers both high speed and high peak torque capability without compromising on the smooth operation and long life.
The new 40mm motor is available in two variants: with embedded fan and air inlets (55mm length), or with a plain housing (44.2mm length).
It provides unparalleled torque and power density, with limited core losses over a wide range of working speeds without friction & brush wear. The 40mm motor can sustain peak torque during 2s up to 1.1Nm, and the maximum speed is 30,000 rpm.
This new motor provides high speed despite the low voltage availability while delivering higher peak torque capability. The embedded fan allows significant heat dissipation to maintain a low operating temperature under heavy load, which ultimately improves productivity. We offer a new package reference within the 40mm diameter motor range, allowing ergonomics gains and comfort thanks to its extremely low weight.
The 40mm motors can be adaptable in most industrial applications, enhancing the life and reliability of a device without compromising on power and machine throughput and saving energy. The new 40mm is an ideal choice for applications such as battery-operated hand tools (tightening, riveting, strapping, stapling, crimping, cutting, nail gun…), factory automation equipment (fans, vacuum pumps…), robotics, and recreational applications such as golf trolley.
Portescap offers flexibility to customize many parameters, on both the electrical and mechanical sides. Coil variations and mechanical interface modifications can enhance the system integration.
Upon request, Portescap can also provide options for specific application requirements.
We designed these motors with key targets in mind:
- 2 variants: without or with integrated fan
- Lengths: 44.2mm without fan / 55mm with fan
- No-load speed: up to 30.000 rpm @ 18V
- Weight: 230/240g (w/o - w/ fan)
- Peak torque capability: 1.1 Nm during 2 seconds
