High Voltage DC Brushed Motor 90V 180V- Suzhou Retek Electric Technology Co., Ltd.

High Voltage DC Motor: Powering Industrial and Medical Equipment

The High Voltage DC Brushed Motor is specifically designed to operate on elevated DC supply voltages (e.g., 90V, 180V, 240V), bypassing the limitations of standard low-voltage DC motors (12V/24V).

Running at high voltage drastically reduces the required operating current for a given power output (P=V⋅I). This allows for the use of thinner wiring, less power loss (I2R), and enables the motor to deliver significant power (up to several horsepower) over longer distances, making it ideal for large fixed industrial machines that convert standard AC mains to high DC voltage via a rectifier bridge.

Frequently Asked Questions

Common Inquiries Regarding High Voltage DC Motors

Q: Are these motors more dangerous due to high voltage?
A: They require adherence to strict electrical safety standards regarding insulation and grounding, similar to any high-voltage AC appliance, but they offer efficiency benefits in fixed installations.

Q: Why are SCR drives popular with these motors?
A: SCR (Silicon Controlled Rectifier) drives offer a simple, robust, and cost-effective way to control the speed of a high-voltage DC motor by controlling the average DC voltage applied to the armature.

Q: What maintenance do these motors require?
A: As brushed motors, they require periodic inspection and replacement of the carbon brushes (typically every 2000 to 5000 hours), which is their main wear item.
