76ZYT 78ZYT 76mm78mm brushed dc motor- Suzhou Retek Electric Technology Co., Ltd.

High Power and Torque in 76mm/78mm Brushed DC Frames

The 76ZYT and 78ZYT series represent a higher class of permanent magnet brushed DC motors, utilized in demanding applications that require sustained torque and power up to 800W or more.

The larger frame size provides the necessary thermal mass and surface area to handle the substantial heat generated by high current. These motors often feature high-segment commutators and robust brush mechanisms to ensure reliable current transfer over a long service life under heavy load. They are engineered for high duty cycles and are commonly found in mobility and heavy-duty actuation systems where durability and simple, rugged control are prioritized over the high efficiency of BLDC technology.

Replaceable Brush System: Available with externally accessible brush holders for easy field maintenance and brush replacement, extending the useful life of the motor indefinitely.
High Starting Torque: Excellent performance in overcoming static friction and inertia upon startup, critical for vehicle propulsion.
Simplified Control: Ideal for cost-sensitive controllers that do not require complex sensor feedback or sinusoidal commutation.

Frequently Asked Questions

Common Inquiries Regarding 76/78ZYT Motors

Q: How does the higher voltage option (up to 96VDC) benefit the motor?
A: Higher voltage reduces the current required for a given power output, significantly lowering I2R losses, improving efficiency, and simplifying the high-current cabling requirements on the vehicle or system.

Q: Why is the brush replacement feature important for this series?
A: In high-duty-cycle applications, brushes are the wear-out component. The ability to replace them in the field without removing or dismantling the motor assembly minimizes maintenance time and overall cost of ownership.

Q: Can these motors be used with regenerative braking?
A: Yes. Brushed DC motors inherently function as generators when back-driven, allowing them to easily implement regenerative braking by routing the generated current back to the battery pack via the motor controller.
