Perhaps the only clue that the new Brammo Empulse is an electric motorcycle is the silence. Yet the bike is so powerful that it set a new lap record at the Infineon Raceway during the all-electric motorcycle grand prix race series, TTXGP, on May 15. With a top speed exceeding 100 mph, the Empulse clocked a lap time of 1:55.150 on the 2.5 mile track, easily winning the competition. Its average lap speed was within 20 seconds of the fastest qualifying lap time of a 1000cc internal-combustion superbike on the same track.
The Brammo bike uses a Parker MPP traction motor that propels the Empulse at breakneck speeds. Features include:
Internal Cooling – This patent-pending technology increases the continuous torque output and virtually eliminates the peak region of the motor.
External Cooling – Allowing for very high motor speeds, Parker’s combination of cooling and packaging give the MPP traction motor on the Empulse a power density higher than that of most – if not all – traction motors available today.
Broad Scalability – Available in more than 15 sizes, the MPP gives users peak output from 25KW to 375KW. Parker’s proven design has the most utility of any motor for the EV/HEV drivetrain.
