English: regenerative brake
Welsh: brêc atgynhyrchiol
Subject: Trafnidiaeth
Welsh definition: A regenerative brake is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used immediately or stored until needed. This contrasts with conventional braking systems, where the excess kinetic energy is converted to unwanted and wasted heat by friction in the brakes.
Plural: breciau atgynhyrchiol
