HT Series
Brand: SMAC CorporationThe HT is a new revolutionary high torque brushless DC motor. Compared to other brushless motors, the HT Motor has a flat torque–speed curve meaning that the speed is less influenced when the torque is increased.
The secret to that is found how the magnetic circuit is built.
A combination of SMAC’s patent pending Halbach magnets and printed coil technology achieves higher torque/amp.
Most small motors run at high RPMs but have low torque.
These are not well fitted for robotic applications.
Expensive and heavy gears are required to get to the required torque.
Higher currents and/or voltages are needed to get useful torques.
Features- A combination of SMAC’s patent pending Halbach magnets and printed coil technology
- Printed coil allows coil shapes impossible to achieve with conventional windings.
- Rotary encoder 2K or 24K optional
- Gear ratio 4:1 or 16:1 optional (Other ratio available upon request.)
- Competitive pricing
